Quartz-feldspar-lithic (QFL), and feldspar composition from the Cenozoic deposits of Weihe Basin, central China
Description
The Quartz-feldspar-lithic (QFL), and feldspar composition data in the sediments can provide valuable information on the provenance and the weathering intensity of the sediments. Traditionally, the QFL composition is identified under binocular microscope. In this dataset, all data were obtained by a novel method of Quantitative Evaluation of Minerals by Scanning Electron Microscopy (QEMSCAN). We applied this methods on a nearly continuous Cenozoic deposits of the Weihe Basin, Central China, which can provide information about the history of weathering intensity over the past 46 Ma. Two tables of data are included. Table 1 is the Quartz-feldspar-lithic (QFL) data determined by QEMSCAN method. The grain counts of monocrystal and coarse grained k-feldspar, plagioclase, albite and quartz, carbonate, the number of all particles, and the calculated quartz-feldspar-lithic composition of all samples are shown. The sources and formations of the samples are also labeled. Table 2 is the number of grains of albite, K-feldspar, Ca-plagioclase and the ratios of Ca-plagioclase/all feldspar (Ca%), albite / K-feldspar (Na/K-feldspar), and Ca-plagioclase/albite (Ca/Na-feldspar) of all samples in this study are shown. The sources and formations of the samples are also labeled.
