Abstract:
OBIECTIVE To study the appearance characters, crystal morphology and trace element content of quartz from three different producing areas, in order to provide experimental basis for the processing and medicinal use of quartz. METHODS The crystal morphology and trace element contents of 23 quartz samples from Dachang Town, Qinglong County, Guizhou Province, Yata Town, Ceheng County, Guizhou Province and Badu Town, Tianlin County, Guangxi Zhuangzu Autonomous Region were studied by microscope and inductively coupled plasma mass spectrometry. OriginPro 2018 software was used for cluster analysis and multivariate principal component analysis of trace elements. RESULTS The white quartz in Badu area was mainly opalescent and lumpy coarse veined. Under the microscope, the white quartz was mainly granular and its surface was dark gray. In Dachang area, white quartz was often symbiosis with stibnite, and part of white quartz was light green. Under the microscope, white quartz was mainly veined and granular, and presents wavy extinction. The white quartz in Yata area was transparent and translucent, and the white quartz particles had a high degree of self-shape, and the white quartz surface could be seen grease luster. The common trace elements in white quartz included lithium(Li), aluminum(Al), titanium(Ti), vanadium(V), chromium(Cr), nickel(Ni), copper(Cu), zinc(Zn), gallium(Ga), arsenic(As), rubidium(Rb), strontium(Sr), yttrium(Y), antimony(Sb), barium(Ba), lead(Pb) and so on. The contents of trace elements in quartz from the three producing areas vary greatly, with the content ranging from lower than the instrument detection limit to 7 772.36 μg·g-1. The highest content was Al element. The contents of Al and Sb in white quartz from Dachang area were obviously higher than those in other areas, and the content of Al could reach 1 846.94-7 772.36 μg·g-1. CONCLUSION White quartz from the different regions of the morphology, microstructure, trace elements have obvious difference, in the same area of white quartz in trace elements has certain inner link, white quartz of Dachang area because contain higher content of neurotoxic element Al and heavy metal element Sb, so in the use of white quartz in the region should be considered as a source of medicinal materials.
