岩浆岩—沉积岩区物理参数与原生晕关系的试验研究
A TENTATfVE STUDY ON THE RELATIONSHIP BETWEENPHYSICAL PARAMETERS AND PRJMARY ANOMAUESIN A MAGMATIC-SEDMENTARY ROCK AREA
【摘要】 在湖南省香花岭锡、铅、锌多金属矿区进行了岩石物理性质与原生晕关系的研究。对与成矿有关的癞子岭岩体、尖峰岭岩体及其围岩的153件样品进行了物性、化学成份分析,得到密度σ、磁化率κ、剩余磁化强度J_r及克氏比值Q等四个物理量和Pb、Zn、W、Sn、Ag、Mo、Be等七个成矿元素的含量。研究发现,物理参数与元素含量之间具有显著的相关性,它们的异常对应性很好。因此,利用这种相关性可以进行地质勘查或成矿预测。
【Abstract】 :A study of the relationship between physical properties of rocks and pri-mary anomalies was conducted in the Xianghualing tin, lead and zinc polyme-tallic ore district in Hunan Province, and physical and chemical analysis wasmade for 153 samples from the ore-related Laiziling rock body and Jianfenglingrock body as well as their wall rocks. As a result, four physical parameters(density σ, magnetic susceptibility k, residual magnetization Jr and a specificratio Q) and contents of seven metallogenic elements (Pb, Zn, W, Sn, Ag, Moand Be) have been obtained. Studies reveal the existence of obvious correlationbetween physical parameters and element contents, and their anomalies arein good conformity. Such correlation can therefore be used to perform geologi-cal exploration and metallogenic prognosis.
