study on main fork changing place characteristics of branching river course in, idle and lower course of changjign river 長江中下游分汊河道主支汊易位特性研究
ore area locate on, silver factory ditch-ancient tomb ditch in west branch river set lower bench, stratigraphic succession, rock assemblage are different with circumference . most is a set of intraclast congeries silica rock . in search of it, its distribution range in the silver factory ditch-ancient tomb ditch 礦區(qū)所在部位銀廠溝?古墓溝一帶,西岔河組下段地層中,地層層序、巖石組合特征與周邊地區(qū)存在明顯的差異。主要為一套內(nèi)碎屑堆積的硅質(zhì)巖。
lode country assume silllike-similar silllike, and the next big anastigmatic, ground and west branch river set strench are consistent . it suffer the gravel silica rock, arena silica control . a handful of lode country or main lode country byway little orebody assume vein, or have the characteristic of balk reappear, compound of branch . these manifest the obvious characteristic of ore construct control 礦體以層?似層狀產(chǎn)出為主,其次為大的透鏡狀,地表延伸與西岔河組地層一致。受礫屑硅質(zhì)巖、含礫砂屑硅質(zhì)巖控制。少數(shù)礦體或主礦體旁側(cè)小礦體呈脈狀、或具尖滅再現(xiàn)、分支復(fù)合特征。
from the characteristic of district geochemistry, we can figure out, cu, ag, pb, zn abnormality main spread along the west branch river set and close to border layer, and the rock chemistry analysis prove, west branch river set have the higher ag chemical element abundance, the cu have the characteristic of asymmetry distribute, and display the migration of element in the late multiphase tectonic activity 從區(qū)域地球化學(xué)特征可以看出,cu、ag、pb、zn等元素異常主要沿西岔河組及相鄰層位分布,巖石化學(xué)測量證明,西岔河組在區(qū)域上具有較高的ag元素豐度值,cu元素具不均勻分布特征,顯示出元素在后期的構(gòu)造活動中的活化遷移。
