广西灌阳地区碳酸盐岩层滑断裂构造地球化学系统

THE TECTO-GEOCHEMICAL SYSYTEM OF THEINTERLAYER-GLIDE FAULT IN THE CARBONATE FORMATION,GUANYANG, GUANGXI

灌阳地区碳酸盐岩中的层滑断裂构造地球化学系统具有典型的结构分带性、变形二重性和成分互补性。在这个系统中存在着Cu→Fe3+→V→Si→Al→Mn→Ba→Ni→Sr→Ag→Bi→Ga→In→Pb→Fe2+→Cr→Co→Zn→Mg→Ca→CO2的稳定性递减序列。影响构造地球化学分异的因素是原岩的性质、应力、温度和流体。构造地球化学作用的基本类型有：动力分异作用、压溶作用和氧化还原作用。层滑断裂带并非还原环境，碳质富集源自有机碳的氧化。Sr是高应力环境同构造重结晶方解石带的特征元素，Zn是低应力环境裂隙充填型方解石脉的特征元素。

The tecto-geochemical system of the inter layer-glide fault in the carbonate formation,Guanyang possesses typical structural zoning, double deformation and compositional complemen-tarity. In this system, there is exists the descending succession of stability: Cu→Fe3+→V→Si→Al→Mn→Ba→Ni→Sr→Ag→Bi→Ga→In→Pb→Fe2+→Cr→Co→Zn→Mg→Ca→CO32-.The facetors affecting the tecto-geochemical differenti action is the character of the primary rock, stress,temperature and fluid. The basic types of the tecto-geoche mical processes include dynamic differ-ent iation, pressure solution and reduction-oxidation. The interlayer glide fault zone is not a reduc-tion environment. The enrichment of carbon is due to the oxidation of organic carbon. Strontium isthe signature element of the calcite resulting from syntectonic crystallization and zinc is the signa-ture element of the calcite of fracture filling type.
