Pyroelectricity of Pyrite and Application to Prospectingin Taibai Gold Deposit
-
摘要: 通過載金礦物黃鐵礦熱電性研究,得出本區黃鐵礦以P型和N-P型導電為主.P型含量高及高的熱電系數絕對值指示有利于金礦化,并由此推測可能的有利成礦部位.雙王成礦帶從西向東,其N型出現率從高到低,反映了從西向東礦體的剝蝕率從大到小,根據黃鐵礦熱電系數計算得出的熱場分布與石準立等(1989)利用含鐵白云石中包體均一法測溫所得出的溫度場相同,對黃鐵礦熱電性與賦礦圍巖之間對應關系及可能原因也進行了討論。Abstract: Studies on pyroelectricity of pyrite have been made in taibai gold deposit, Shannxi Province. Pyrite occurs maily N-P-type and p-type electricity conduction (N-electronic conduction,p-hole conduction). High P-type content and high absolut value of pyroelectricity coefficient indicated the good mineralization.From upper to lower of the ore body, from west to east of the ore belt, the P-type content is going down.That shows the denudation rate of ore body from large to small. Contour map of absolute value of pyroelectricity coefficient and isothermal map calculated from pyroelectricity shows that the deep and east of KT8 is the prospective ore area.The pyroelectricity differs with the kind of wallrock that may be result of the difference of deep of ore-forming.
