The Jiama deposit in Tibet is a very typical polymetallic deposit in the Gangdise metallogenic belt. Through theoretical prediction and research, it is believed that concealed porphyry-skarn ore bodies are developed in the deep part of the ore concentration area. However, the exploration model based on the borehole coverage of the mining area has a low degree of prediction of the potential target area in the peripheral area. In this paper, based on the density, magnetic properties, resistivity, and polarizability data of 45 borehole cores in the Jiama deposit, we inverted and analyzed the three-dimensional magnetotelluric sounding data volume covering the Jiama deposit and its periphery. At the same time, based on the GOCAD software platform, through discrete smooth interpolation and stochastic simulation algorithms, we constructed the stratum lithology-geophysical three-dimensional visualization integrated model of the Jiama deposit. Combining the results of 2D geological interpretation of 11 magnetotelluric (MT) profiles, we have finely depicted the development characteristics of 3D skarn bodies below 3000m, and verified them with the Jiama Scientific Deep Drill JMKZ-1 well, which was not involved in the modeling, and the results show a consistency agreement. Besides, by combining the skarn metallogenic model, analyzing the characteristics of the electrical parameters of the Jiama deposit and adjacent areas, and combining the electrical characteristics of the three-dimensional skarn, we predict the favorable Target area of stratified skarn in Jiama deposit. The results of this study provide a demonstration of 3D modeling technology for the evaluation of deep resource potential and the goal of increasing reserves in the mining area.

Displacement is an important parameter reflecting the characteristics of slope dynamics. The displacement data set is obtained by arranging one displacement measurement point at each of the toe, middle, shoulder and top of the counter-bedding model slope, collecting displacement data every one minute, correcting the collected data and deleting the abnormal data at the end of each point, and obtaining the displacement data set of the counter-bending rock slope shaking table model test; The displacement data set of the model slope under the same working condition can reflect the relationship between the displacement of the toe, middle, shoulder and top of the slope under such seismic action, and the displacement data set of the model slope under different working conditions can reflect the damage mechanism of the counter-beddomg rock slope with the accumulation of seismic action.

Holding particular biological resources, the Tibetan Plateau is a unique geologic-geographic-biotic interactively unite and hence play an important role in the global biodiversity domain. The Tibetan Plateau has undergone vigorous environmental changes since the Cenozoic, and played roles switching from “a paradise of tropical animals and plants” to “the cradle of Ice Age mammalian fauna”. Recent significant paleontological discoveries have refined a big picture of the evolutionary history of biodiversity on that plateau against the backdrop of major environmental changes, and paved the way for the assessment of its far-reaching impact upon the biota around the plateau and even in more remote regions. Here, based on the newly reported fossils from the Tibetan Plateau which include diverse animals and plants, we present a general review of the changing biodiversity on the Tibetan Plateau and its influence in a global scale. We define the Tibetan Plateau as a junction station of the history of modern biodiversity, whose performance can be categorized in the following three patterns: (1) Local origination of endemism; (2) Local origination and “Out of Tibet”; (3) Intercontinental dispersal via Tibet. The first pattern is exemplified by the snow carps, the major component of the freshwater fish fauna on the plateau, whose temporal distribution pattern of the fossil schizothoracines approximately mirrors the spatial distribution pattern of their living counterparts. Through ascent with modification, their history reflects the biological responses to the stepwise uplift of the Tibetan Plateau. The second pattern is represented by the dispersal history of some mammals since the Pliocene and some plants. The ancestors of some Ice Age mammals, e.g., the wholly rhino, Arctic fox, and argali sheep first originated and evolved in the uplifted and frozen Tibet during the liocene, and then migrated toward the Arctic regions or even the North American continent at beginning of the Ice Age; the ancestor of pantherines (big cats) first rose in Tibetan Plateau during the Pliocene, followed by the disperse of its descendants to other parts of Asia, Africa, North and South America to play as top predators of the local ecosystems. The early members of some plants, e.g., Elaeagnaceae appeared in Tibet during the Late Eocene and then dispersed and were widely distributed to other regions. The last pattern is typified by the history of the tree of heaven (Ailanthus) and climbing perch. Ailanthus originated in the Indian subcontinent, then colonized into Tibet after the Indian-Asian plate collision, and dispersed therefrom to East Asia, Europe and even North America. The climbing perches among freshwater fishes probably rose in Southeast Asia during the Middle Eocene, dispersed to Tibet and then migrated into Africa via the docked India. These cases highlight the role of Tibet, which was involved in the continental collision, in the ntercontinental biotic interchanges. The three evolutionary patterns

Under the background of global warming, the cryosphere is one of the most sensitive spheres to climate change. The cryosphere is the world's largest reservoir of freshwater resources. The change of the cryosphere has an important impact on the energy exchange, water resources, ecology and disaster process of the earth atmosphere system. Therefore, it is particularly important to explore the response of cryosphere change to climate change. Using satellite remote sensing data, reanalysis data, and observation data, the cryosphere elements were integrated to build a global scale cryosphere range and phenology dataset for 1979-2016. The results can be used to further study the response mechanism of the cryosphere to climate change, as well as to provide basic support for the research of ecosystems, carbon cycle, etc.

Acceleration is an important parameter to reflect the dynamics of slope. Fifteen acceleration sensors are arranged on the slope surface, lithological interface and inside the slope of the Xuelongnang counter-bedding rock model slope. An acceleration sensor is arranged on the shaking table to record the real acceleration state of the input seismic wave. The collected data are filteringed, noise reduction, screened and other processing steps to obtain the acceleration data set of the counter-bedding rock model slope; The peak values of the acceleration data of the model slope under the same load condition can reflect the dynamic response law of the slope under such seismic action, and the ratio of the peak acceleration on the slope to the peak acceleration on the table can reflect whether the slope is enhanced or attenuated at each location under the seismic action.

During the development of debris flow monitoring microwave radar prototype, a series of demonstration applications were carried out in tianmogou, Bomi County, Nyingchi Prefecture, Tibet Autonomous Region. The test alarm data and application alarm data information in the demonstration application were reported and recorded through the multi-mode communication unit. This record gives the report records during the test and application. The data is the original log records exported from the background database of the control center, which are listed in Excel table according to the display of the control center, so as to improve its readability. Because the debris flow microwave radar is a result oriented monitoring, that is, its monitoring results directly give whether there is debris flow, rather than the relevant conditions of debris flow. Therefore, this data is mainly used to determine the target recognition ability in the research and development process of debris flow monitoring microwave radar. The data can be used as a reference for the development of debris flow microwave radar.

The Wuyu Basin is bounded by the Gangdese Mountains to the north and the Yarlung Tsangpo River to the south, and is a representative basin to study the Cenozoic tectonism of the southern Tibet. The sedimentary strata in the Wuyu Basin include the Paleocene-Eocene Linzizong Group volcanics and the Oligocene Rigongla Formation (Fm.) volcanics, the Miocene lacustrine sediments of the Mangxiang Fm. and Laiqing Fm. volcanics, the late Miocene-Pliocene Wuyu Fm., and the Pleistocene Dazi Fm. Five sandstone samples from the Mangxiang Fm., Wuyu Fm. and Dazi Fm. and one modern Wuyu reiver sand sample were collected for detrital zircon U-Pb dating using the LA-ICP-MS method. Detrital zircon U-Pb ages in the Mangxiang Fm. show a large cluster at 45-80 Ma; those in the Wuyu Fm. show a large cluster at 8-15 Ma and a subsidiary cluster at 45-70 Ma; those in the Dazi Fm. show three large clusters at 45-65 Ma, 105-150 Ma and 167-238 Ma; and those in modern Wuyu river show a large cluster at 8-15 Ma and a subsidiary cluster at 45-65 Ma (Figure 1). Late Cretaceous-early Eocene zircons in all samples are consistent with the most prominent stage of magmatism of the Gangdese Mountains; the 8-15 Ma zircons in the Wuyu Fm. and modern Wuyu river are consistent with the magmatism of the Laiqing Fm.; and the Triassic-Jurassic zircons in the Dazi Fm. are consistent with the magmatism of the central Lhasa terrane. The results of detrital zircon U-Pb ages and sedimentary facies analyses in the Wuyu Basin indicate that the southern Tibetan Plateau suffered multi-stage tectonism-magmatism since the India-Asia collision: (1) Paleogene Linzizong Group-Rigongla Fm. volcanics; (2) tectonism-magmatism at ~15 Ma ended the lacustrine sediments of the Mangxiang Fm. and resulted in volcanism of the Laiqing Fm.; (3) tectonism at ~8 Ma resulted in the volcanic rocks of the Laiqing Fm. becoming one of the main provenances for the overlying Wuyu Fm.; (4) the Wuyu Basin formed braided river and received sediments from the central Lhasa terrane to its north at ~2.5 Ma. The geomorphic pattern of the southern Tibet has gradually formed since the Quaternary.
