Two types of granitoids,highly deformed augen granitoids and undeformed fine-grained granitoids,are widely distributed in Gangou area,Central Tianshan Mountains,Northwest china. The augen granitoids are high-K calc-alkaline characterized by high K2O,Rb,Y and Th,and low Sr and Sr/Y. They also have high contents of large ion lithophile elements (LILE),such as Ba,Rb,K and Th,and relatively low con-tents of high field strength elements (HFSE),such as Zr,Y and Nb. The fine-grained granitoids are calc-alkaline characterized by high Sr,low Y and HREE,similar to adakitic rocks,and with Na2O/K2O2 (1.76―1.91),high ISr (0.70689―0.70981),and negative εNd(t ) (-2.4―-5.3). High-precision SHRIMP U-Pb zircon dating results indicate that the Gangou augen granitiods were formed at 428 ± 10 Ma,and the fine-grained granitoids were emplaced at 361―368 Ma. These geochemical and U-Pb zircon data have significant implications for the timing of closure of the Mishigou-Gangou Ocean and the evolution of the Central Tianshan orogenic belt.

Located in the eastern portion of the Xing’an-Mongolian Orogenic Belt(XMOB),the Xinkailing-Kele complex has previously been considered to be Precambrian metamorphic rocks,mainly according to its relatively high metamorphic *** filed observation,however,revealed that the complex is composed mainly of metamorphic rocks(Kele complex),tectono-schists("Xinkailing Group"), and granitoids(Xinkailing granitic complex).Dating on these rocks using advanced SHRIMP zircon U-Pb technique indicates that:(1) Biotite-plagioclase gneiss from the Kele complex has a protolith age of 337±7 Ma(2σ) and a metamorphic age of 216±3 Ma(2σ);(2) the tectono-schist of the"Xinkailing Group"gave a magmatic age of 292±6 Ma(2σ),indicative of felsic volcanic protolith of the schist formed in Late Paleozoic time;and(3) the Menluhedingzi and Lengchuan granites of the Xinkailing granitic complex were emplaced at 167±4(2σ) and 164±4 Ma(2σ),*** results suggest that the Xinkailing-Kele complex is not Precambrian metamorphic rocks and the so-called Precambrian"Nenjiang Block"does essentially not *** combination with regional geological data,we propose that the Kele metamorphic complex is likely related to a collisional tectonism that took place in Triassic time,as indicted by its metamorphic age of 216±3 *** Xinkailing granitic complex was emplaced along the collisional zone during Mid-Jurassic time, likely in a post-orogenic or anorogenic setting.

A new rock type of granite,approximate 45 km in area and located about 10 km south of Xilinhot,Inner Mongolia,was found in the Sunitezuoqi(or called Suzuoqi) -Xilinhot tectonic belt and identified as an A-type miarolitic *** pluton has miarolitic structure and is composed chiefly of perthite,quartz,euhedral albite and potassium *** types of textures occur in the pluton,such as perthitie,graphic and myrmekite textures. Only quartz is found in miarolitic *** A-type granite with seagull-shaped REE patterns and obvious negative Eu anomaly(δEu=0.24—0.28) is high in SiO(76%—77%),K and Na(NaO+KO=7.75%—8.15%) and low in Ca(CaO =0.20%—0.22%),Fe and *** petrographical observations and chemical compositions indicate that it is an A-type *** SHRIMP U-Pb analyses indicate that this A-type granite was emplaced at 276±2 Ma and coeval with the same type of granites in the adjacent ***,it suggests that this pluton was likely formed in a post-orogenic extensional setting and probably related to break-off of subducted slabs in Central Asian Orogenic Belt(CAOB),which indicate that the Sunitezuoqi-Xilinhot belt was tectonically evolved into post-orogenic stage since early Permian.

致密油的分布呈现大面积低丰度含油背景下局部富集的特征,亦只有在富集区内才能获得可观的商业油流。因此,甜点区的优选是致密油地质研究的重点。为分析致密油的富集规律,服务致密油甜点评价,以四川盆地侏罗系大安寨段为例,依托油田详实的生产数据,运用成藏物理模拟实验、显微薄片、场发射扫描电镜资料,并结合综合地质成图,对致密油的富集主控因素进行了研究。结果表明,研究区致密油的富集具有强烈的非均质性,占总井数22.5%的高产井产出了84.4%的油气,致密油富集程度的差异在盆地和区带尺度的分布上持续存在,并分别受不同因素的差异化控制。在盆地尺度下,受二次运移的影响,烃源岩只能控制致密油的分布外边界,在有利烃源岩区内部无法严格约束甜点区分布。在区带尺度下,有利沉积相带控制了致密油富集区带的分布。致密油富集甜点受有利成岩相和裂缝的控制。基于上述认识,建立了一套致密油富集甜点评价参数体系,为致密油甜点选区提供支持。

四川盆地中部地区侏罗系凉高山组滩坝相砂岩是致密油重要产层。生产数据表明,该储层非均质性强,亟需明确有利储层类型及其分布的主控因素。针对凉高山组湖相三角洲—滩坝沉积体系,利用岩心、露头、录/测井、岩石薄片、地球化学和古地貌等资料,应用湖侵—湖退体系域划分方法及沉积微相精细划分技术,识别不同级次的层序,精细剖析层序演化过程及其控制下的储层的成因类型和有利储层分布。提出凉高山组沉积时期湖平面的升降控制了滩坝的形成与发育,滩坝主要分布于湖侵体系域。并将滨浅湖滩坝进一步划分为坝(坝主体、坝侧缘)、滩(近岸滩和远岸滩)2个微相,认为凉高山组有利储层受沉积微相控制,浅湖砂坝主体砂岩为有利储层。最后初步优选2个致密油勘探有利区,明确了滩坝相有利储层分布规律,对下步勘探决策有指导意义。
