山东招远北截金矿床地质特征及深部成矿预测

对北截金矿的矿床与矿体地质构造及成矿模式和构造应力场的综合研究表明，北截金矿主要是受ＮＥ向的灵山沟－北截断裂控制，其储矿构造部位与与断裂带小角度斜交的ＮＮＥ向张剪性断裂，矿体主要分布于其中的２号矿带之中，矿体之间呈右行斜列为ＳＷ深部发展；百区内的ＮＷＷ向断裂为成矿后断裂，对矿体有较小的破坏作用；对矿区内Ａｕ、Ａｇ、Ａｓ、Ｍｏ、Ｓｂ、Ｂｉ进行的微量元素原生晕及Ａｇ／Ａｕ、Ａｓ／Ｍｏ与Ｓｂ／Ｂｉ比值分

Heat influx and exhumation of the Shimanto accretionary complex: Miocene fission track ages from the Kii Peninsula, southwest Japan

Abstract   To determine how local geological events contributed to the evolution of accretionary complexes and eventual exposure of rocks with different structural levels, geochronological mapping was carried out using fission track (FT) analysis at the Kii Peninsula, southwest Japan. At this site, the original zonal structure of Cretaceous accretionary complexes parallel to the subduction zone is disturbed by the northward projection of the Shimanto accretionary complex. Twenty-six zircon FT ages were obtained from an area of ∼12 km in an east–west direction and ∼15 km in a north–south direction, and classified into three groups: (i) ages ∼15 Ma (range ∼10–20 Ma), which are distributed along the northwest–southeast valley; (ii) ages of ∼50 Ma in the northwest of the study area; and (iii) ages older than those in Groups 1 and 2. Based on results from eight zircon FT length distributions, the Miocene ages appear to be the result of spatial variations in heat influx and cooling after the regional exhumation of the area, as recorded by FT ages of ∼50 Ma.

山东省夏季高温气候变化特征分析

对比分析山东省夏季1961～1990年和1971～2000年前后30年极端最高气温和高温日数的分布和变化，得知山东省夏季高温的气候变化存在明显的地域性差异，东部地区高温有所增多，西部地区明显减少。利用统计方法分析山东省各地高温多年变化特征，发现夏季高温日数和极端最高气温均存在明显的年代际变化，且东西部变化不尽相同；在60年代末70年代初全省夏季极端最高气温发生了一次转折性变化。     

鲁西平邑地区磨坊沟金矿床的流体包裹体研究

选择鲁西平邑磨坊沟和梨方沟两个矿区的矿化蚀变样品,对保存于石英、方解石和萤石中的原生包裹体及氢、氧稳定同位素进行了详细的研究。研究表明,二个矿区的包裹体大小、形态相似,类型一致,均为气液两相盐水包裹体。包裹体的均一温度变化范围较宽,在120～450℃之间均有分布,但主要集中于120～260℃的范围内,可进一步分为110～150℃和170～250℃两个区间。结合显微镜下观测的载金矿物的特点,推测金矿的形成温度区间在170～250℃之间。冰点变化范围较大,在-2 8～-11 5℃之间,对应的盐度在4 65%～15 47%之间。矿体及围岩黄铁矿的δ34S值介于-0 71‰～+2 99‰之间,方解石和石英的δDSMOW值为-63‰～-70‰,δ18OSMOW值为+18 4‰～+22 2‰。以上数据表明流体来源于地幔,成矿过程中与建造水发生了混合。

胜利油区孤南洼陷古、新近系充填层序与沉积环境

孤南洼陷是济阳坳陷沾化凹陷的一个新生代次级洼陷。边界断层的活动差异性造成洼陷形态为典型的南超北断的箕状洼陷；多次的构造运动形成了湖盆的多次抬升剥蚀和沉降。充填序列可以划分为4个构造层序；沉积体系可划分出河流、扇三角洲、三角洲及湖泊体系等4种；洼陷的沉积受同沉积构造活动及物源补给状况的控制。     

Preliminary study on the occurrence of geothermal systems in the tectonic compressional regions: an example from the Derman geothermal field in the Biga Peninsula, Turkey

There are numerous hot springs with temperatures ranging from 30 to 100 °C in Biga peninsula and they occur throughout the peninsula. The result of this study shows that the region is under a tectonic compressional regime. The investigation of the faults and fractures in the region indicates that the region has been affected first by N–S and then E–W compression since the Middle Miocene. Opening fractures and antithetic and synthetic faults due to the compressional movements provide paths for the deep circulation of water. In addition, the tectonic movements, granitic intrusion and volcanic activity have also played important roles as heat sources for the geothermal systems.     

Diagenetic paths in the margin of a Triassic Basin: NW zone of the Iberian Chain, Spain

Buntsandstein deposits generated in a slowly subsiding basin on the western margin of the Iberian Chain are represented by a stratigraphic succession of fluvial deposits less than 100 m thick (conglomerates, sandstones, and shales). Diagenetic processes in sandstones can be grouped as eodiagenetic, mesodiagenetic, and telodiagenetic. Eodiagenesis can be associated with Muschelkalk, Keuper, and probably early Jurassic times. Mesodiagenesis is probably related to Jurassic times. Diagenetic chemical reactions suggest a maximum burial less than 1.5 km and low temperatures (<120°C). Patterns of porosity reduction by compaction and cementation suggest four diagenetic stages: (1) Loss of primary porosity by early mechanical compaction; (2) early cementation (K-feldspar and dolomite); (3) dissolution of cements; and (4) framework collapse by re-compaction. These stages are manifested by the presence of two types of sandstone. Type I sandstones present high intergranular volume (mean, 30%). Type II sandstones are characterized by high compactional porosity loss and exhibit low values of intergranular volume (mean, 16.9%). Type II sandstones are associated with the dissolution of cement and later re-compaction of type I sandstones. An intermediate telodiagenetic phase is deduced and related to the sharp unconformity between Lower Cretaceous sediments and the underlying sediments. This suggests that a mechanically unstable framework collapsed during the Cretaceous, generating type II sandstones. The analyzed diagenetic paths have a wide applicability on similar marginal areas of rift basins.
