Magnetic and Geochemical data set of Huitoutala section, Qaidam Basin (2017)
1) Data content:
Paleomagnetic data can establish paleomagnetic time frame, magnetic and geochemical indicators can restore the climate change in geological history, and heavy mineral analysis can be used to trace provenance.
2) Data sources and processing methods
Data sources are experimental data.
Magnetic data: The samples collected in the field were ground into fine particles in a 2x2x2 non-magnetic plastic box with a mortar, and tested with a Kapobridge magnetometer, pulse magnetometer and rotary magnetometer.
Carbon isotope data: The samples were dried at 40℃, then studied to less than 200 mesh, and reacted with 100% phosphoric acid to release CO2 gas in a gas source isophase mass spectrometer.
Grain size data: Analysis of decomposed samples using a Malvern Mastersizer 2000 particle size analyzer. Prior to analysis, organic matter was removed with hot hydrogen peroxide and then carbonate was removed with hydrochloric acid in accordance with standard Procedures of Lanzhou University.
3) Data quality
Sample collection and experimental processing were carried out in accordance with strict standards, and the data obtained were of reliable quality.
4) Data application achievements and prospects
One SCI paper was published using the data, which was Ni.
The magnetic and geochemical data are stored in the file "HTTL 2017 (6-10MA).xlsx", where HTTL stands for the abbreviation of the profile name, 2017 stands for the year of data publication, and 6-10MA stands for the years included in the data
