Abstract

The structure of rock formation in Wuxu ore-concentrated area likes“sandwich” without the exposed magmatic rocks， ore body is located in the middle of “sandwich”which is mudstone layer.Characteristics of construction of vein and the distribution of veins flat surface and section in Jianzhupo deposit of Wuxu ore field is analyzed and the results show that the ore body is formed in brittle-ductile thrust shear zone in the early phase of Indo-Chinese epoch.Orebody sank in the shape of echelon deeply， thenitwasreformedbytheWuxufaultpropagation fold in the late phase of Indo-Chinese epoch afterwards and SN fold in the phase of Yanshanian， at last its strike is NNWanddistributionlookslikepositively“eight” Chinesecharactersinthesection.The late reformation make sore body attitude of westwing and the core department of anticline uprightly，and ore body of westwing sinking from SW to NE deeply.It’ scontrolled directly by the distribution of right/lefte chelon vein in the early indosinian brittle-ductilethrustshearzone.Itconcludesthattherockstratahavea “sandwich” intheNandan-Hechimetallogenicbelt， arelikely tooccurbrittle-ductileshearbeltwhichcontrolveinorebody.

Key words： “sandwich” like rock formation; D R type rupture; brittle-ductile shear zone; fault propagation fold; Nandan-Hechi metallogenic belt; Guangxi Province
