作者方维萱,黄转盈（2019）在《沉积盆地构造变形序列Ⅰ：秦岭晚古生代拉分盆地的构造组合与金-铜铅锌多金属矿集区构造》一文中研究指出：研究秦岭晚古生代拉分盆地构造变形序列、构造样式、构造组合与卡林型-类卡林型金矿床、SEDEX型银铜铅锌-重晶石-菱铁矿矿床富集成矿之间关系,对提升秦岭金属矿集区构造与金属大规模富集成矿规律的认识,具有重要意义。陕西柞山和凤太晚古生代拉分盆地是卡林型-类卡林型金矿矿集区和SEDEX型银铜铅锌矿集区,采用构造岩相学研究新方法,对晚古生代拉分盆地的构造变形序列、构造样式和构造组合、构造变形型相及与金-铜铅锌矿床改造-叠加成矿作用进行研究。认为秦岭晚古生代陆缘拉分盆地的构造变形序列和构造组合为:（1）在石炭纪—中三叠世陆-陆斜向俯冲消减体制下盆地反转期,构造-热事件和构造岩相学组合类型包括石炭纪—二叠纪构造-热事件、顺层走滑伸展变形与深源碱性热流体叠加事件,形成了泥盆系中顺层剪切变形[DS1（D-S0//S1）]、Na-K-Cl-F型热流体渗滤交代岩相[DS1a-h-S1//S0+S1#S0]、碱性热流体叠加构造岩相[DS1（FB-D3j+D3x）]和热液叠加角砾岩构造系统[DS1c（Ab-D3）],为中深构造层次（20.4～25.97km）韧性变形域下形成的变形构造型相。形成了柞山地区穆家庄铜矿床和桐木沟铅锌矿床,热液角砾岩构造系统以柞山万丈沟—二台子金铜矿床和凤太双王—青岩沟金矿床为代表。（2）在印支期陆-陆全面碰撞挤压体制下,在晚古生代陆缘拉分盆地内部,盆内变形构造组合和构造-岩浆热事件为冲断褶皱带+W-M型复式褶皱-压扭性断裂带+切层脆韧性剪切变形（DS2）+隐伏岩浆侵入构造系统,它们为中构造层次（11～17km）脆韧性变形域下形成的变形构造型相。在柞山晚古生代陆缘拉分断陷盆地南北两侧边界同生断裂带,转变为南向厚皮型逆冲推覆构造系统,夏家店造山型金矿床受山阳—凤镇断裂带的镇安—板岩镇次级断裂和厚皮型冲断褶皱带控制,金矿体定位于切层和顺层脆韧性剪切带中。凤太晚古生代陆缘拉分盆地南北两侧边界同生断裂带,转变为对冲式厚皮型逆冲推覆构造系统,八卦庙—柴玛沟—丝毛岭金矿带受印支期反冲构造、冲起构造与隐伏岩浆侵入构造系在时间-空间-物质上多重耦合控制,金矿体定位于切层脆韧性剪切带中。WM型复式褶皱-压扭性断裂带对SEDEX型铜铅锌矿床改造富集成矿控制显著,受W-M型复式褶皱-压扭性断裂带和次级横跨叠加褶皱控制,SEDEX型银铜铅锌-重晶石-菱铁矿矿床发生了改造富集成矿。（3）燕山期陆内造山期的构造组合为白垩纪陆内断陷成盆+岩浆侵入构造系统+接触热变质相带+脆性断裂-节理-裂隙变形（DS3）,为浅构造层次（0.0～5.0km）变形域中形成的变形构造型相,在柞山地区具有寻找斑岩型铜金银钼矿和夕卡岩型铁铜金矿的潜力。卡林型金矿矿集区发育印支期和燕山期冲断褶皱带、断裂+褶皱构造、节理-裂隙带和低温热液角砾岩化（碧玉质化角砾岩、铁白云石化热液角砾岩、菱铁矿化热液角砾岩等）,为脆性构造变形域中形成的变形构造型相。（4）喜山期以陆内走滑断裂和宽缓褶皱等脆性构造变形为主。在金-银铜铅锌矿集区构造和变形构造型相与金-银铜铅锌富集成矿关系上,受山阳—礼县岩石圈断裂带（山阳—凤镇断裂带、观音峡—修石崖断裂带）控制,泥盆纪盆内同生构造组合为同生断裂带+三级构造热水沉积盆地+热水沉积岩相系,它们为控制SEDEX型银铜铅锌-重晶石-菱铁矿矿床的主要同生构造型相。石炭纪—白垩纪深源碱性热流体隐爆作用和异时同位叠加成岩作用,形成了铁白云石钠长角砾岩-钠长铁白云石角砾岩相系,它们组成了热液角砾岩构造系统。铜金银镍钴成矿系统深部结构以万丈沟岩浆热液脉带型铜金银镍钴矿和二台子热液角砾岩型铜金矿为代表,向上为双王热液角砾岩型金矿床和八卦庙式金矿床,其顶部和外围为类卡林型-卡林型金矿床。
