2、土厚、露頭少的特點(diǎn),宜采用高精度瞬變電磁法(TEM)和音頻大地電磁法(AMT)等物探技術(shù)探測(cè)靈北斷裂帶“主斷裂”及其上盤次級(jí)斷裂位置和深部變化情況;U號(hào)遠(yuǎn)景區(qū),位于七厘山礦區(qū),鑒于主礦體走向延長(zhǎng)較大及上盤遙感泥化蝕變異常和Au—Ag—Cu—As—Sb元素組合異常的情況,在其深部尋找“第二富集帶”可做為一個(gè)主要找礦方向,宜選擇典型剖面開展音頻大地電磁法(AMT法)測(cè)量,探測(cè)400m以下深度的斷裂帶及低阻異常分布位置,為鉆探工程驗(yàn)證提供依據(jù);II號(hào)遠(yuǎn)景區(qū),位于靈北斷裂帶鳳凰莊段。發(fā)育Au—Ag—Cu-As—Sb元素組合異常和金礦化,針對(duì)該區(qū)露頭發(fā)育、化探異常清晰的
3、特點(diǎn),宜采用大比例尺構(gòu)造與蝕變填圖,結(jié)合構(gòu)造地球化學(xué)法加密,查明靈北斷裂帶主帶及次級(jí)含礦或蝕變斷裂的找礦潛力與找礦有利部位。關(guān)鍵詞:找礦預(yù)測(cè);找礦方法;黃埠嶺金礦;靈北斷裂帶中圖分類號(hào):P611文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1004—4051(2015)08—0089—03DiscussiononoreprospectsandprospectingmethodsofdeepandperipheralsofHuangbulinggolddepositinthenorthwestofJiaodongpeninsulaCONGPei-zhang,XUGuo—ming。,Y
