Paleomagnetic and Paleoclimatic data sets of Dahonggou section in Qaidam Basin, China


1) Data content:

Paleomagnetic data, magnetic index data, major element percentage data and chemical weathering index can establish the paleomagnetic age framework of the Dahonggou section and restore the precipitation change and chemical weathering history in geological history.

2) Data sources and processing methods

The data source is experimental data.

Paleomagnetic data: a cylindrical sample of 2x2x2cm was drilled with a small gasoline drill and measured with a low-temperature superconducting magnetometer in a magnetic shielding room.

Magnetic data: the samples collected in the field were ground into fine particles by mortar and put into 2x2x2 non-magnetic plastic box, and tested by kappa bridge susceptibility meter, pulse magnetometer and rotating magnetometer.

Mass percentage content and chemical weathering index data of major elements in the whole sample and particle size fraction: firstly, the whole sample and particle size fraction sample were pretreated with acetic acid and hydrogen peroxide to remove carbonate and organic matter, and then pressed into a round cake with a diameter of about 4cm and a thickness of about 8mm by a pressure apparatus, and finally XRF fluorescence analysis was carried out.

3) Data quality

The sample collection and experimental processing are carried out according to strict standards, and the data quality is reliable.

4) Data application achievements and Prospects

Three SCI papers were published using this set of data, one of which is Ni.


Data file naming and use method

The file is named by location and data content, such as dhgpmag, where DHG represents the sampling location of Dahonggou section and pmag represents paleomagnetic data.
Open it in Excel and you can use the data.
