    • 摘要: 大陆科学钻探是“入地”的重要手段,是“深入地球内部的望远镜”.中国大陆科学钻探事业开展15周年以来,取得重要进展,获得全球地学界的高度关注,特别是2001年实施的中国第一口大陆科学深钻(5158m),成果辉煌,影响巨大.继后,又开展了青海湖环境科学钻探、松辽盆地白垩纪科学钻探、柴达木盐湖环境资源科学钻探,汶川地震断裂带科学钻探以及中国大陆科钻资源集成计划,总共钻进约35km,显示了中国科学钻探方兴未艾的景象.为纪念国际大陆科学钻探20周年(1996~2016)和中国大陆科学钻探实施15周年(2001~2016),本文回顾中国大陆科学钻探实施15年来的艰辛和奋斗的历程,展望中国大陆科学钻探的未来.

    • 摘要: 为了更有效地利用测井资料识别岩性,以中国大陆科学钻探工程主孔超高压变质岩的测井与岩心化学分析资料为对象,研究两者之间的内在关系。从相关文献中搜集和整理了主孔的189个岩心样品的全元素分析资料,提取了岩心分析与测井响应的样本数据。在此基础上,分析了氧化物含量与常规测井响应的统计关系,并通过逐步线性回归方法,建立了氧化物含量的测井评价模型。利用测井资料,计算主孔72~2010 m 井段地层的氧化物含量,对主孔地层岩性和钛矿(化)发育特征进行解释。研究表明,对于复杂的变质岩类,常规测井响应与地层元素组分之间存在内在的联系;在获得岩心全元素分析数据的条件下,利用测井资料建立地层化学组分的评价模型,能够为岩性与含矿分析提供更为直接的数据。%Well logging is facing more and more questions about complicated lithology interpretation.In or-der to identify lithology effectively by taking well logging,logging and core test data of main holes in super high pressure metamorphic rocks from Chinese Continental Scientific Drilling Project(CCSD)as examples, internal relations between conventional logging data and element component of stratum have been studied. Whole elements analysis information of 189 pieces of core samples have been collected,and the sample data of core analysis and corresponding logging datas have been extracted.On these basis,statistical relation-ship between oxide contents and normal corresponding logging datas has been analyzed.By using stepwise linear regression method,logging evaluation model of oxide content has been established.The oxide con-tents of main holes in 72 ~2010m section have been calculated by using logging data,and lithology and mineral development characteristics of main holes have been explained.It is showed that immanent connec-tion exists between conventional logging response and element component for the complex metamorphic rock.On the condition of gaining element analysis data,by using well logging data,evaluation models of chemical components in strata has been set up.It can provide more direct data for lithology and ore analy-sis.

    • 摘要: Diamonds from eclogite in main hole of the Chinese Continental Scientific Drilling Project (CCSD-MH) on the Sulu ultrahigh-pressure metamorphic (UHPM) belt were formed by the deep subduction of continent crust,while diamonds from the Luobusa ophiolitic chromitites in the Yarlung Zangbo suture of Tibet were originated from the deep mantle.Thus,their formational background and mechanism are much different.A primary analysis of FT-IR show that UHPM diamonds are Ⅰ aAB type,and the ophiolitic diamonds are Ⅰ aA type,both are different in the way of gather and evolvement for N-impurity.The FT-IR data show that the diamonds from the two locations are natural diamonds,and the UHPM diamonds might formed earlier than the ophiolitic diamonds.%大别苏鲁超高压变质带上的大陆科学钻探主孔(CCSD-MH)中榴辉岩中的金刚石形成于大陆深俯冲作用过程,西藏雅鲁藏布江缝合带罗布莎蛇绿岩铬铁矿中的金刚石来自深部地幔,两者的形成背景和机制可能不同.本文对两地的金刚石样品开展了傅立叶变换红外光谱(FT-IR)定性分析.结果表明,西藏罗布莎金刚石样品为ⅠaA型;而CCSD-MH金刚石为ⅠaAB型,既表明其杂质氮的聚集形式和演化路径上存在着差异.红外光谱特征不仅仅表明两者属天然金刚石常见类型,并且超高压变质带中的金刚石形成时间可能更久远.

    • 摘要: 中国大陆科学钻探(CCSD)井位于苏鲁超高压变质带南部的东海县境内.井区地震勘探是钻探综合研究项目之一,该项目采用世界先进的数字地震仪和三分量数字检波器,对line 1线剖面进行了测量.依据地震勘探成果和CCSD岩心资料,通过对该地震剖面深部构造反射特征的详细分析,发现该区深部反射构造具有明显的三单元层结构.第一单元层,约在11km内,出现6个强反射带,产状基本一致,倾向SE,倾角28°.岩心资料和VSP勘探资料证实前4个反射带主要是榴辉岩带和韧性剪切带的反射,榴辉岩带与片麻岩成不规则层状相间分布.第二单元层,约在11~30 km,有4个比较清楚的反射带,反射弱,连续性差,带内分布有不规则的弱反射.其产状也基本一致,倾角很小,比较平缓,由浅到深,倾向逐渐变为NW,它与第一单元层为角度不整合接触关系.第三单元层,约在30 km以下深度,其顶部出现了比较强的反射带,连续性较好,产状较平缓,倾向NW;而在顶部反射带以下,则反射均匀,没有不规则反射带.据上述反射特征,结合该区地质背景,推测第一单元层为中朝与扬子板块俯冲带的折返地壳层,第二单元层为扬子克拉通层,主要为变质岩层,第三单元层为上地幔层,其顶部的反射为莫霍面的反射.%Chinese continental scientific drilling (CCSD) well is located in Donghai County which lies in the southern part of Sulu ultra-high pressure metamorphic zone. The seismic survey is one of the multi-scientific integrated research projects. The well has been surveyed by world advanced digital seismic instrument (HF300) and three component digital geophone (geochain). Combining the achievement of seismic survey and the information of rock core 5 000 m-CCSD, and through detailed analyses of deep structure reflection characteristics of seismic profile, we found that there is a three-unit-layer structure in the deep area. Six strong reflection bands appeared within 11 km in the first-unit-layer with the basically consistent attitudes, the trend is SE and the dip angle is 28 degree. The rock core sample and the VSP exploration data confirmed that the front four reflection bands are mainly the reflections from the eclogite and the ductile shear zone. The eclogite zone and the gneiss are distributed as irregularly alternative layers. Four quite clear reflection bands appeared between approximate ll km to 30 km in the second-unit-layer, whose energy is weak, and the reflection continuity is poor. There are some weak anomalous reflections among the four bands. Their attitudes are also consistent basically, however, the dip angle is very small and the trend changes gradually to NW from shallow area to deep area. The interaction relation between the first-unit-layer and the second-unite-layer is angular unconformity. Only one quite strong reflection band appeared below approximate 30 krn in the third-unit-layer,whose continuity is good; the attitude is gentle and the trend is still NW. However, the reflections are even and there isn't any anomalous reflection below the reflection band. According to the reflection characteristics and the geologic background mentioned above, we speculate that the first-unit-layer is the turned back terrane from the subduction zone of the Yangzi and Sino-Korean plate; the second-unit -layer is the Yangzi Craton; the third-unit-layer is the upper mantle, and the reflection of its top is from the Moho interface.
