Geological and geochemical studies demonstrare that the metallogensis of gold deposits are related to magmatie hydrothermal solution and mineralizations of different types are charterized by their metallogenesis with those from same source, and of same epoch and genesis deposited in place in different apace.
It shows from the geological and geochemical characteristics of the two gold deposit that they belong to the series of the interstratified glide breccia type gold deposits with the same genesis and source which are formed in the similar geological condition.
By using the isochronic tracking correlation technique of base-level cycle analysis and high-resolution strtigraphic framework,two types of isochronic sandbody correlation model of both "equielevation,nonsynchrone,hetero-origin" and "unequal-elevation,synchrone,identical genesis" are supposed in Chang 8 oil formation of the Xifeng oil field.
According to the X-ray powder diffraction pattern, the cell parameters of K-feldspars can be counted by electronic computer and its variations may be used to estimate the Al/Si ordering distribution in the feldspar framework. The composition and structural states of K-feldspars have shown that they are different in two granitoid bodies which constitute Taiping Huangshan polygenetic composite granitoid bath olith.
Gold deposits in the Xiongershan area, Henan occur principally in altered rocks of fractured zones. Those occurred in explosion breccia pipes also hold an important place. Geological and geochemical studies demonstrare that the metallogensis of gold deposits are related to magmatie hydrothermal solution and mineralizations of different types are charterized by their metallogenesis with those from same source, and of same epoch and genesis deposited in place in different apace. Guide for exploration is sugge...
Z pluton is one in which Uranium is comparatively rich.The Uranium mainly comes from the massif of later stage.Yenshan epoch by studying on mineral (Pb) (that intergrow with Uraninite ) pyrite and U-Pb isotope evolution system of epoch granite and features of mineral deposit.The Urani- um of epoch granite is associated with the formation bed (Ar) and the Pb isotope of age-Old bed is re- mained.
