| 摘 要： | 在水系沉积物中进行重砂矿物取样仍然是寻找以矿体或含矿母岩为目标体的主要手段之一,但对于金刚石矿干扰体很多。金伯利岩中与金刚石伴生的镁铝榴石、铬铁矿、钛铁矿和透辉石风化后形成以金伯利岩为中心的分散晕,在水系沉积物中采集KIM并进行分析可以有效地排除干扰体,进而不断地接近真正的目标。

| Abstract: | Sampling of heavy placer minerals in stream sediments is still one of the main methods for tracing ore bodies or their host rocks. However, there are many interfering bodies in diamond prospecting, such as the dispersed halo of magnesium-aluminite, chromite, ilmenite and diopside, whic are associated with diamond in kimberlite, centered on kimberlite. The collection and analysis of KIM in drainage sediments can effectively eliminate interfering bodies, and get closer and closer to the real goal. |
