摘要
本文通过对黑龙江省新生代富钾及富钠碱性玄武岩进行了熔融与淬火实验研究。确定了岩石固相线与液相线的温度,岩石结晶程度与温度的关系。研究了矿物结晶的温度区间与顺序、晶体形态及习性。讨论了压力对岩石熔点的影响、岩石酸度与粘度、结晶程度的关系以及熔体有序状态对矿物形态的影响。
Described in this paper are the melting and quenching experiments on K-rich and Na-rich Cenozoic alkali basalts from Heilongjiang Province. Solidus and liquidus temperatures of the rocks and relationship between crystallinity and crystallization temperature have been determined. Crystallization temperature range and sequence of minerals, as well as the forms and habits of crystalls are studied. Effect of pressure on melting points of the rocks, relationship between the acidity and vicosity and crystallinity of the rocks, and effect of the ordered state of melts on the forms of minerals are discussed as well.
