2.
The intensive ductile shearing deformation and complicated alkali metasomatism are well developed in the Shut-Quan-Gou alkaline complex.
在印支－燕山期，冀西北水泉沟碱性杂岩体角闪二长岩遭受了强烈的韧性剪切变形和复杂的碱交代作用，逐步演化出角闪二长糜棱岩类→碱交代正长岩类→钾长花岗岩类，以及东坪、黄土梁、小营盘等几十处石英脉钾—质蚀变岩型金矿床，形成独特的含金碱性杂岩体，揭示了冀西北崇礼—赤城含金剪切带重要的碱交代成岩成矿机制。
5) contact metasomatism
接触交代
1.
