| Abstract: | These "green-bean rocks" at the base of Middle Triassic Leikoupo Formation in Longmen-dong, Emeishan, Sichuan, have been studied with analyses of chemical, thermal, infrared absorptionspectroscopy, X-ray diffraction, polarized-light and electron microscopes. These analyses indicate thatmain components of "green-bean rocks"are K-rich illite clays in which there are dispersed siliceouspisolites and a little montmorillonites. In general, mineral components are relatively simple, and theyhave a considerable distribution size. It is known that their K grade can meet the industrial requirementsfor minerals. These K-bearing rocks can be used as a variety of potash fertilizers. The results of this study that these "green-bean rocks" was originated from eruptive volcanic ashdeposited in a supratidal-tidal flat environment and reformed through syngenesis-diagenesis. |
