| 摘 要： | 出露地表或近地表的矿体,在遭受风化剥蚀作用时,稳定地向水系补充矿化物质,形成在矿体附近具有浓集中心,含量向下游逐渐衰减的水系沉积物异常,对这种异常的形成作用称之为“稳定流”。应用这一概念,可以筛选化探异常。进一步根据“稳定流”的长度和强度,还能够近似定量地推断未知矿化区面金属量(Ps)以及建立典型矿床水系沉积物元素分带序列,为寻找隐伏矿体,评价区域化探异常提供了一种新的方法。

| Abstract: | Subjected to weathering, a outcropping orebody, or near the ground-surface, steadily and continuously supplies mineralized material into waters and then produces anomaly of geochemical prospecting, which the content of mineralized material gradualy decreases downstream and there is concentrating centre near the orebody. This kind of anomaly is defined by the author as Stable Geochemical Flow. By the concept, various anomaly of regional geochemical prospecting can be chosen related with orebody. Based on the length and strength of Stable Geochemical Flow, areal productivity in unknown mineralized area can be worked out, zoning sequence of elements in stream sediment from a typical ore deposit can be set up, so as to find out a blind ore deposit. This is a new effective method for assessing anomaly of regional geochemical prospecting. |
