为了研究小灶火地区黒沙山岩体的成岩环境、时代、构造环境、地区化学等特征

为了研究小灶火地区黒沙山岩体的成岩环境、时代、构造环境、地区化学等特征，对岩体的主量元素、微量元素、稀土元素、同位素年龄等样品数据的统计分析，岩体成岩时代为晚三叠世；主量元素总体显示偏铝质-高钾钙碱性花岗岩的成分特点，具I型和S型花岗岩类特征；成岩阶段经历了强烈的结晶分异及同源岩浆演化，是海西—印支造山运动进入陆陆碰撞阶段向造山后造山带伸展崩塌阶段转折时期的产物。

In order to rock environment, age and tectonic environment, chemical characteristics of small area fire area black rock hill, statistical analysis of major elements, trace elements and rare earth elements in rock samples, isotopic age data, rock diagenetic age of Late Triassic three; major elements showing metaluminous composition characteristics - high-k calc alkaline granite, with I type and S type granite characteristics; diagenetic stages experienced strong crystal fractionation and comagmatic evolution is the Hercynian Indosinian orogeny, into the continental collision stage extensional collapse stage of product transition to the post orogenic orogenic belt.
