Major conclutions from this study can be summarized as following:1. On mineralogy, rutiles, apatites, epidotes and vein minerals from UHPM rocks were firstly and systematically studied, by detailed petrography and mineral-chemistry investigation, some mineral or mineral assemblage with special composions or texture were firstly found in UHPM rocks from Sulu-Dabie, for example, corrudum, magnesite, high-Ti biotite and garnet were found as inclusions in rutiles from eclogites, Nb-Fe rutile and zoned Si-Y apatite were found in gneiss, epidote / allanite with euhedral zones like magmatic genesis were found in elogites and gneiss, a lot of minerals with high REE, HFSE, LILE and volatiles were found in veins of gneiss.

在矿物学方面，首次较为系统地研究了超高压变质岩中的金红石、磷灰石、绿帘石等副矿物，并通过详细的岩相学和矿物化学研究，首次在苏鲁-大别超高压变质岩中发现了一些具有特殊成分/结构的矿物或矿物组合，如在榴辉岩金红石中发现了刚玉、菱镁矿、高钛黑云母和石榴石矿物包裹体，在片麻岩中发现了Nb-Fe金红石和具有自形环带结构的高Si-Y磷灰石，在榴辉岩和片麻岩中发现了具有类似岩浆成因的自形生长环带结构的绿帘石/褐帘石，在片麻岩的脉体中发现了大量富含稀土元素REE、高场强元素HFSE(Nb、Ta、Zr、Ti)、大离子亲石元素LILE(K、Th、U、Sr、Ba)，以及挥发性组份(CO_2、F、P、S)的特殊矿物，丰富并提升了超高压变质岩的矿物学研究。2。

The late period of loess accumulation with high contents of hornblende and epidote is mainly far-source sedimentary with wind transport, and the early and middle periods of loess accumulation with high contents of magnetite and dens are mainly near-source sedimentary with complex transport.

普通角闪石、绿帘石含量较高的黄土堆积后期是以远源沉积为主，且以风力搬运为主；磁铁矿、岩屑含量较高的早、中期是以近源沉积为主，搬运动力较复杂。

The existence of fine intergrowth of low Fe epidote and clinoepidote in the glaucophane schist from Mulan Mountain, Hubei province has been confirmed by the analytical data from electron probe microanalysis and optical microscopic analysis.

电子探针和光学显微镜联合分析表明，木兰山蓝片岩中存在斜黝帘石-低铁绿帘石连生体。

Those MEp that occurred as subsolid mineral with or without resorption of earlierformed hornblende, can be use as pressure indicator for intrusion.

而晚期近固相线晶出的绿帘石时，能够作为压力计反映岩体最小侵位深度。据此可以应用于对地壳演化和隆升的研究。

MEp which crystallized earlier than biotite or hornblende in the magma, can not be used as a barometer, but be useful in caculating the ascent speed of magma.

作为早期结晶的矿物，绿帘石不能作为压力计来反映岩体侵位深度，因为在绿帘石晶出时，岩浆中液相体积在50%～80%，这样岩浆可能会有快速侵位的过程，但它的地质意义在于能够对岩浆上升速率做出估算。

Is around ore shoots to be distribute with symmetry, that show the block and brecciated ores of the Tongmugou zinc deposit are fluid metasomatic reformed deposit.

后生流体交代岩（主要由透闪石、绿帘石、透辉石、黑云母、石英、绿泥石等矿物组成）显著受层间断层控制，它是流体交代原热水沉积层和热水沉积闪锌矿纹层而形成的，该矿床为热水沉积-流体交代改造矿床。

The coesite-diamond-bearing eclogite distributed in the northern part of the UHPM belt suffered three stages of metamorphism. The first stage is the Ep amphibolite facies metamorphism, which is represented by the paragenesis of phe+Qtz+Cro/Bar Bar+Ep+Ab occurred as inclusions in Grt and Omp; The second stage is the peak metamorphism of eclogite facies with mineral assembledge of Grt+Omp+Coe±Dia±Ky±Zo±Phe+Rt. The P -T condition is 800±50℃,≥28Kb; The third stage is the amphibolite facies retrograded metamorphism from the peak one, which can be divided intothe early amphibolite facies stage with the mineral assembledge of Amp+ Pl+Di+Qtz±Ep+Ilm/Ttn and the late greenschist facies one with the mineral assembledge of Ep+Chl+Bi+Tr+Ab.

分布于超高压变质带北侧的柯石英榴辉岩经历了3个阶段的变质作用：(1)早期绿帘—角闪岩相阶段，以出现在石榴石和绿辉石中的包体矿物多硅白云母、石英、冰蓝闪石或青铝闪石、钠长石等为代表；(2)峰期柯石英榴辉岩相阶段，其矿物组合为Grt+Omp+Ky+Phe±Zo+Coe±Dia+Rt，其变质温度压力为800±50℃，≥28Kb；(3)退化变质作用阶段，早期为角闪岩相，以Amp+Pl+Di±Ep+Qtz+Tit等退变矿物组合为代表；晚期为绿片岩相，以绿帘石、绿泥石、黑云母、透闪石及钠长石等矿物为代表。

Epidotes from different samples show considerable compositional variation,whereas those from the same sample are quite similar in composition, indica-ting that their composition is related.

s=0.23—0.37，但多为0.30—0.32，在不同样品中绿帘石成分变化很大，但同一样品中绿帘石变化不明显，说明其成分与全岩成分有关。
