前言汤山金矿点的发现是1980年我队对宁镇地区进行岩石地球化学测量普查中发现的。82年我队又在该区开展了包括整个汤山短轴背斜在内的7KM~2的岩石地球化学测量详查工作。通过工作认为:(1)在奥陶系中、下统(O_1 h+d、O_2 t、O_3 t)的碳酸盐岩中存在一个金的高背景(矿源层)层位。(2)测区的主要地质、地球化学特征与卡林型金矿的主要地质、地化特征基本相似。具有一定的找矿意义。测区地质概况测区位于宁镇穹断褶束转折部位,局部构造为一穹窿状短轴背斜,向西倾伏。背斜北翼地层出露较全,东南翼受断裂影响下跌,被第四系复盖。出露地层以寒武系上统及奥陶系的
Foreword The discovery of the Tangshan gold deposit was discovered in a 1980 general survey of the rock geochemistry of the Ningxia area by our team. In 1982, the team carried out a detailed survey of rock geochemical survey of 7KM ~ 2 including the Tangshan short axis anticline in the area. Through the work, it is considered that: (1) there is a high background (source rock) gold layer in the carbonate rocks of the Lower Ordovician (O_1h + d, O_2t, O_3t). (2) The main geological and geochemical characteristics of the survey area are basically similar to the main geological and geochemical features of Carlin-type gold deposits. Has a prospecting significance. Geological survey of the survey area is located in the transitional part of Ningzhen dome fold, local structure as a dome-shaped short axis anticline, Pilian west. The anticlinal north-wing stratum exposed more, the southeast wing fell under the influence of the fracture and was covered by the Quaternary. Exposed to the Cambrian strata and Ordovician strata
