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。
Further research of lithofacies pvove : lode country output points belongs to tidal - flat facies . and the two sides belong to littoral facies - estuarine facies . ore area petrochemistry analyse also prove : intraclast congeries silica rock in basin have higher cu , ag abundance than circumference pena . the prominence inhomogeneity of the cu distribution indicates reconstruct of the late construction 礦區(qū)內(nèi)巖石化學(xué)測量也證明:盆地內(nèi)發(fā)育的內(nèi)碎屑堆積硅質(zhì)巖比周圍巖石具有更高的cu 、 ag元素地球化學(xué)豐度值, cu元素分布的顯著不均一性,表明了后期構(gòu)造的改造作用。
