归来庄金矿矿体和岩体中Au等成分的Runs检验及意义

Runs检验是研究序列分布规律的一种数学方法.用这种方法检验归来庄金矿和铜石杂岩体的某些成分,得出归来庄金矿TC30中Au的高品位值的出现不是随机的,而是具有集中出现的规律性;铜石杂岩体中SiO2和Au都是具有随机变化性,说明杂岩体没有明显的演化关系,不同岩体的形成时间先后对成矿元素Au的富集没有明显影响;杂岩体中Al2O3和TiO2比值在闪长玢岩和二长斑岩中无明显差异,说明二者为同源成因.

RUNS TEST FOR AU, SiO2, AL2O3/TIO2 IN THE GUILAIZHUANG GOLD DEPOSIT AND TONGSHI COMPLEX

Runs test is a mathematic method to study sequence distribution. Using the method to test contents of Guilaizhuang gold deposit and Tongshi complex, it is concluded that distribution of high Au grades in orebody in trench TC30 is not random, but aggregated. In Lijiachun-Shizipou magmafic section, it is known that the distribution of Au and SiO2 is at random through runs test analysis. These show that there is no evolutionary relationship between diorite-porphyrite and monzonite. Au does not show affinity to any magmatic body. The distribution of Al2O3/TiO2 is also at random by runs test, this means two magmatic bodies in Tongshi complex are homologous.
