    • 摘要: 通过闽台梯级过渡带及台湾海峡深部高温岩体成岩、成矿地质响应自西往东、由北向南梯度增强、形成年代渐新的叙述,映衬研究区深部高温岩体热物质活动强度自西往东、由北向南增强的趋势十分明显,表明:台湾海峡深部高温岩体热物质上涌、运移、变异、交换活动最强烈;次之是闽东燕山断陷区的闽台梯级过渡带东部;再次之是闽东燕山断陷区的闽台梯级过渡带西部;福建大陆西部受台湾海峡与闽台梯级过渡带深部高温岩体活动的影响较大,其中西部的闽西南坳陷区深部高温体成岩、成矿地质响应程度明显要比闽西北隆起区强烈.

    • 摘要: 利用铸体薄片、阴极发光、扫描电镜、包裹体测温及X衍射分析等实验测试方法,对东濮凹陷上古生界潜山致密砂岩储层的岩石学特征、成岩作用,及其对储层孔隙演化规律的影响进行了研究.结果 表明:潜山致密砂岩储层储集空间以次生溶蚀孔隙为主,通过建立孔隙定量演化模式,明确了山西组-太原组合煤储层孔隙演化与石千峰组-上石盒子组储层存在差异;潜山致密砂岩储层成岩演化阶段整体处于中成岩A-B期,石千峰组-上石盒子组储层具有早胶结、晚溶蚀的特点,储层次生孔隙更发育,山西组-太原组合煤储层具有早溶蚀、后压实、晚胶结的特点,成岩过程中储层快速致密.石千峰组-上石盒子组储层早期方解石胶结增加了抗压实能力,为后期溶蚀作用提供物质基础,在总体致密化背景下成为相对有利的油气勘探目标.

    • 摘要: Mineralogical and geochemical properties of microbialites collected from the Permian-Triassic boundary in Chaohu, Anhui Province were studied.Besides, experiments on the dissolution of microbialites by HCl were carried out for probing the separation condition between calcite and ankerite.The results show that the samples are homogeneous in composition, with high Si, Al and Mn contents.Calcite, quartz, clay minerals and ankerite are the main phases.Most of the ankerite particles are euhedral, showing either triangle or diamond forms on cross section, and their sizes are roughly equal(~10 μm).Under the conditions that HCl concentration was 0.3% and solid-to-liquid ratio was 1∶50, calcite in microbialites was dissolved totally, while leaving ankerite undissolved.It is suggested that microbialites in the Permian-Triassic boundary was formed under anoxic condition;microorganisms promoted the formation of clay minerals, while had no effect on the formation of carbonates;ankerite was formed through three stages: Fe-carbonate was formed during sedimentation, Fe and Mg was released during diagenesis, Fe and Mg entered into calcite, leading to local dolomitization.%文章对安徽巢湖地区二叠系-三叠系界线微生物岩进行了化学成分和矿物组合分析,同时探索了盐酸溶解法分离样品中不同种类碳酸盐矿物的方法.结果表明,界线微生物岩成分均一,具有较高的Si、Al和Mn含量,主要由方解石、石英、黏土矿物和铁白云石组成,岩性上为泥质、白云质灰岩;岩石中的铁白云石自形程度较高,截面呈正三角形或菱形,晶粒大小在10 μm左右;采用0.3%HCl(固液质量比1∶50)可以有效区分微生物岩中的方解石和铁白云石(前者溶解,后者不溶).研究认为:二叠系-三叠系界线层微生物岩形成于缺氧条件下;微生物促进了黏土矿物的生成,对碳酸盐矿物的生成无影响;铁白云石的生成经历了含铁碳酸盐沉积-碳酸盐去Mg、Fe作用-铁白云石化过程.

    • 摘要: 对位于厄瓜多尔中新世金属成矿带的Beroen金银矿床不同位置的英云闪长岩和花岗闪长岩进行锆石U-Pb定年及地球化学研究。结果表明:加权平均年龄分别为(15.92±0.4) Ma和(34.73±0.7) Ma。结合两个岩体的地球化学特征对比,认为由于俯冲洋壳板片脱水后,交代软流圈地幔楔形成相似的母源岩浆在后期演化过程中差异化,渐新世的花岗闪长岩母源岩浆在区域伸展应力背景下上侵,倾向发育斜长石的结晶分异。而英云闪长岩是深层熔浆在上侵过程中受到挤压应力作用影响造成停滞形成的,熔体在中下地壳层进行以角闪石(±榍石)为主的结晶分异作用。构造背景的改变与Beroen绢云母蚀变形成时间都在中新世,成矿作用与中新世岩浆侵位有密切关系。%Beroen gold deposit is part of central Andean miocene metallogenic belt. Zircon U-Pb dating of intrusions of Beroen:tonalite, granodiorite, indicates that tonalite has emplaced in middle Miocene, granodiorite had emplaced in early Oligocene, with weighted average age of (15.92±0.4) Ma and (34.73±0.7) Ma, respectively. Combined with their geochemical characteristics, both intrusions melt derived similarly from slab dehydration fluids fluxing mantle wedge partial melting, then experienced different evolution process. The Oligocene granodiorites were emplaced in a crustal domain extension and emplaced through trench-parallel and trench-normal faults and sutures, through a continuous passive ascent process, with undergoing more plagioclase differentiation. The Miocene tonalite emplaced under compressive stress background with trench parallel structures was sealed. The magmas were thus impeded to rise, ponded and undergone mainly amphibole differentiation at lower crust. The sericite in orebody formed prior to emplacement of tonalite. Maybe Beroen mineralization was resulted from the geodynamic transition of extension condition to compression condition induced by subduction zone’s geodynamic changing.

    • 摘要: The article summarizes the progress on concept definition,metallogenic tectonic geological conditions,and features,metallogenetic fluid characteristics and cryptoexplosive breccia diagenetic and metallogenetic mechanism of cryptoexplosive breccia and the breccia type gold deposits.Such deposit is prolific in the ancient land activation area,Mesozoic fault basin edge or island arc volcanic belt of the Pa-cific Rim.The ore body is spatially and temporally related closely to hypabyssal-ultra shallow acidic por-phyry bodies and occurs at top of the body which are alkali-rich and silicon-rich and belongs to "I" type granite.When pressure of the high heat energy thermal fluid at top of the body is greater than the sum of the tensile strength of the surrounding rock and the minimum principal stress cryptoexplosion occur and the cryptoexplosive breccia is formed.Commonly the cryptoexplosive breccia cylinder is vertically zoned as crack phase 、shattered phase、blasting phase、channel phase.Breccia size tends horizontally to be smaller from center to edge.The Instant burst of ore-forming fluid in a closed system creates a semi-open or open system and leads to relative large pressure gradient.Pressure of the ore-forming fluid is reduced and the fluid boiled.Mixture,immiscibity of the fluid and water-rock reaction change the physiochemical condi-tion and cause reduction of solubility of gold complexes and the complexes precipitate to be gold minerali-zation.Formation of cryptoexplosive breccia cylinder and evolution of thermal fluid were promoted and o-verprinted sequentially upward from the bottom in the process of “temperature increase-(explosion)boil-temperature decrease-temperature increase-(explosion)-boil-temperature decrease”.“boil-temperature de-crease”is the main ore material precipitation stage.This type of gold deposit is characterized by metallo-genic series and system.Multi-type ores occur in one intrusive body or one cylinder.It is significant to guide further exploration in the area.%文章阐述隐爆角砾岩型金矿床的定义、成矿构造背景、隐爆角砾岩及其矿床特征、成矿流体特征以及隐爆角砾岩成岩成矿模式等方面研究进展。隐爆角砾岩型金矿床多产于古老地块活化区、中生代断陷盆地边缘、滨太平洋岛弧火山岩带内。矿体与浅成超浅成中酸性斑岩具有密切的时空关系,多赋存于斑岩体的顶部。侵入岩具有富碱、富硅特征,属Ⅰ型花岗岩类。当侵入体顶部高热能流体压力大于围岩抗拉强度和最小主应力之和时发生隐爆作用而形成隐爆角砾岩。隐爆角砾岩筒垂向可分为裂隙相、震碎相、爆破相和通道相;角砾粒径从中心到边缘水平分带一般呈由小到大的趋势。成矿流体由于爆发作用瞬间由封闭体系进入半开放或开放体系,产生较大的压力梯度,流体减压沸腾、混合、不混溶和水岩反应等引起成矿元素稳定的物理化学条件变化,导致金络合物的溶解度降低而产生金矿化。隐爆角砾岩筒的形成及流体演化分别具有“自下而上顺次推进序次叠加”和“升温(爆破)沸腾降温升温(爆破)沸腾降温”的演化过程,其中“沸腾降温”阶段为矿质主要沉淀阶段。隐爆角砾岩型金矿的成矿具有“一体多型”“一筒多型”的特点,运用矿床系列成矿系统理论指导勘探找矿具有十分重要的意义。

    • 摘要: 基于琼东南盆地西部崖城地区10余口钻井的实测钻井资料,以及流体包裹体、激光拉曼探针、古压力热动力学模拟、有机地球化学、阴极发光、铸体薄片和碳酸盐胶结物碳氧同位素组成等多项测试分析,剖析了超压顶界面分布以及附近的泄压带流体活动特征,同时揭示了流体活动造成泄压带岩场响应。研究区泄压带可能位于超压顶面附近地层;地层测试、泥浆密度、测井曲线和速度谱资料确定了崖城区现今超压顶面深度主要分布在3 000-4 000 m,而且由构造高部位向低部位加深;各井超压顶面附近的泄压影响范围不同,具体范围可由镜质体反射率Ro得到。现今超压顶面与古超压顶面(泄压流体排放期)深度变化较小。泄压带流体具有相对高温高压、含有酸性和烃类等特征,流体活动使得泄压带成岩场的温压条件和孔隙流体介质发生变化从而影响了水-岩作用;主要表现为:①泄压带地层的Ro和黏土矿物出现提前转变趋势;②有机质Tmax异常小和S1/(S1+S2)异常大;③泄压带储层发生的热流体酸性溶蚀导致次生孔隙带发育;④长石颗粒钠长石化,自生石英和碳酸盐胶结物异常发育,其为深部超压有机流体排放的产物。总之,研究区超压顶面附近的泄压带可能为天然气与优质储层及盖层耦合有利聚集带,是今后琼东南盆地天然气勘探的现实区域。

    • 摘要: 以平湖构造带平湖组中下段为例,基于烃源岩及油气的地球化学特征,尝试利用流体包裹体系统分析技术厘定的油气充注史结合储层岩石学恢复的孔隙度演化史,得到研究区致密砂岩储层成岩演化与成藏之间具有“独特”的耦合关系,从而识别出该区存在2种不同成因类型的致密砂岩油气藏.即第1期(16.2~13.8 Ma)油充注于储层致密化之前,在浮力作用下进入储层,形成“后成型”致密油藏;第2期(5~0 Ma)油气充注于储层逐渐致密化时期,在浮力和毛细管压力共同作用下进入储层,形成“边成藏边致密型”油气藏.同时分别对应2种不同的成藏模式,即“早期侧向充注古构造、晚期改造”的复合成藏模式和“原油从源岩垂向充注于圈闭,同时受后来天然气气侵改造”的成藏模式.

    • 摘要: The reef oil-gas pools are an important target in the oil and gas exploration. Its reservoir quality is of great importance. Generally, the main controlling factors of development of reef reservoir include deposition, structure and diagenesis. The former two have influence over the distribution of the reservoir and the latter determines the quality. In the Middle Permian, reef constructed mainly by sponges was well developed in the Nanpanjiang basin. This article deals with controls of diagenesis over reef reservoir conditions in the Nanpaniiang basin based on thin section observation. The study indicates that the reef experienced the submarine phreatic, freshwater, buried, epigenetic environments in turn and uplifted to the surface to be eroded at last. The diagenesis happened in those conditions includes cementation, dissolution, dolomitization, compaction and pressure solution. The cementation primarily occurred in the submarine phreatic and freshwater environments and accompanied by dissolution with reservoir porosity destroyed to some extent. Going into the shallow buried environment, pore space in the reef was almost filled with cements. Sanking to the middle-deep buried environment, dolomitization and dissolution took place in the reef, which improved reservoir porosity significantly. So the reef under buried environment will be a favorable exploration target.%生物礁油气藏是油气勘探的一个重要目标,其储集性能的好坏是控制它能否成藏的关键。中二叠世南盘江盆地发育以海绵类为主要骨架的生物礁,其经历了海底潜流、淡水、埋藏、表生等成岩环境,最后抬升出露地表遭受侵蚀。所发生的成岩作用主要有:胶结、溶蚀、白云化、硅化以及压实、压溶作用。在前两种环境中,主要是胶结作用,伴随溶蚀,这一阶段储层孔隙性遭到了一定程度的破坏;浅埋藏阶段的胶结最终填满孔隙;而中-深埋藏环境下的有机流体充注溶蚀以及相应发生的白云岩化作用有效改造了储层的孔隙性,该区处于埋藏条件下的台缘生物礁是有利的油气勘探目标。
