岩浆

Based on the detailed field investigation and isotopic data, the stages of magmatic activity in the Nandan-Hechi metallogenetic belt base been hued out in this paper.

本文根据野外地质观察，结合同位素测年资料厘定了丹池成矿带内岩浆侵人期次。

The leucogranites veins occurred widespreadly in the para-metamorphic rocks, in which the hypersthene melagranulite distributed. That suggests the source rocks of leucogranites of the High Himalaya are para-metamorphic rocks. For the basement was uplifting, pressure relieved and lacked water, source rocks were melting partly and formed the leucogranite magma.

基底副变质岩中广泛分布淡色花岗岩脉体，在基底副变质岩中的淡色花岗岩脉体中发现紫苏辉石暗色麻粒岩残留体，这表明本区高喜马拉雅淡色花岗岩源岩为基底副变质岩，且基底副变质岩是在基底快速隆升降压的条件下发生缺水熔融生成的淡色花岗岩岩浆。

Up to now, there are no obvious petrologic and geochemical evidences to prove that the immiscibility during the formation and evolution of pegmatites is resulted from the perphosphorus feature in melt phase.

Positive correlation between Mg~# and P_2O_5 and negative correlation between P_2O_5 and FeO suggest that addition of P is not the key role for the separation of immiscible oxide melts. In contrast, negative correlation between Mg~# and Fe_2O_3/FeO ratios implies that the increasing of oxygen fugacity is very likely the main factor to induce immiscibility of oxide melt.

Mg#与P2O5的正相关以及P2O5与FeO含量的负相关，表明P不是导致氧化物熔体不混熔的主要原因；而Mg#与Fe2O3/FeO的负相关则说明，岩浆演化过程中氧逸度的升高可能是导致氧化物熔体不混熔的主要原因。

According to the experimental results of Watson (1978), and Ryerson and Hess (1980), pertaining to the distribution of trace elements between basic and acidic liquids in the temperature above magmatic liquidus, and the investigation of Webster (1997) on the melt inclusion in pegmatitic quartz from Ehrenfriedersdorf ore district, Germany, it should be drawn that there probably exists the liquid immiscibility in the early stage of pegmatitic evolution, due to the perphosphorus content in the magmatic systems. The perphosphorus feature of the melt is of great impact on the petrogenesis and matellogenesis of pegmatites.
