THE NATURAL HEAVY MINERALS OF GOLD IN LIAONING PROVINCE: Distribution Law and Relationship to Gold Deposits
-
摘要: 辽宁省金自然重砂异常在区域上区带性分布特征明显,在空间分布上划分6个区带.它们受较大规模的构造、赋矿地层、构造岩浆岩带等条件控制.自然重砂异常的形成受控于地质条件、矿物本身的物理化学性质,并与地形、地貌、水文等自然条件有关,但最重要的影响因素是金矿床的空间分布.重砂异常在空间上与原生矿体或含矿岩体密切相关,远较原生矿或含矿岩体范围大.可以利用重砂异常评定一个区域的含矿性和成矿特征,指导找原生矿和砂矿.Abstract: The regional distribution of the natural heavy mineral anomaly of gold in Liaoning Province is characterized by obvious zonation. The natural heavy minerals of gold, which can be divided into six zones, are controlled by large structures, hosting strata and tectonomagmatic belts. The formation of the natural heavy mineral of gold is related to the geological conditions, the physical and chemical properties of the mineral, as well as the terrain, landform and hydrology. The most important factor is the spatial distribution of gold deposits. There is a closely relationship between the heavy concentrate anomaly and primary ore body or ore-bearing rock body. The range of heavy concentrate anomaly is much larger than that of the primary ore body or ore-bearing rock body. The heavy concentrate anomaly can be used to assess regional ore potentiality and metallogenesis.
