前言在苏联西伯利亚曾发生过更新世的高山冰川作用,结果导致大范围的矿床破坏,同时形成了各种类型的冰川沉积。例如,河流沉积物。在一些地方,矿床已被切割深达250—600m。冰川河流沉积物地层与冰碛地层同时产生在高山冰川作用的初期阶段。于冰碛物被堆积和岩坎(冰川山谷底部的横向的基岩脊)形成之后,在砂-粘土质湖泊沉积物中,形成了成矿元素异常。 Preface Pleistocene alpine glaciations have taken place in Siberia, the Soviet Union, resulting in the destruction of a wide range of deposits and the formation of various types of glacial deposits. For example, river sediments. In some places, the deposit has been cut to a depth of 250-600m. Glacial river sediments and moraine strata simultaneously produce the role of alpine glaciers in the early stages. After the moraines were deposited and the rocky ridge (the lateral bedrock ridge at the bottom of the glacial valley), anomalies of ore-forming elements were formed in the sand-clay lake sediments.
