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。

2The studies on the appearance typomorphism, physical typomorphism, inner structure typomorphism and chemical typomorphism of the zircon and garnet, and the result of U-Pb isotopic age dating of zircon indicate that the zircons are meta-morphogenic genesis but two or three of them are magmatic genesis and most meta-morphogenic zircons have a basic magmatic zircon core which was generated in Stage of Yanshand and Indo-Chinese epoch. The genesis and origin of the garnet is very complicated. The garnets are main almandine with high Fe and Mg content and were proposed their souce rocks are mostly regional mid-degree-metamorphic rocks.

2研究锆石和石榴石的形貌标型、物性标型、内部结构标型以及成分标型特征和锆石U-Pb同位素测年结果表明，锆石除少数几个为岩浆锆石外，绝大多数是变质锆石，且中间多有形成于燕山-印支期的基性岩岩浆锆石残核；石榴石的成因及来源是比较复杂的，以铁铝榴石为主，且铁铝榴石中Fe、Mg的含量较高，推测其源区母岩主要以中级区域变质岩为主。
