Keywords: ophiolite Tibet
An unusual mantle mineral group consisting of more than 100 species (or subsp ecies) minerals was discovered in chromite from the Yarlung Zangbo ophiolite bel t, Tibet. It includes native element minerals alloys, oxides (arsenides) and sil icates. According to experimental data, some of the minerals are ultrahigh-press ure minerals, possibly formed at the Earth's core-mantle boundary, and are the p roducts of chemical reactions between liquid iron of the Earth's outer core and silicates at the base of the lower mantle; others might be derived from the lowe r mantle, transitional zone and upper mantle. The mantle mineral group in Tibet has great significance in mineralogy and geodynamics.

Grinding the mixture of kaolin and hydrazine concentrate can not only raise t he speed of intercalation so that the intercalation rate reaches 96 % in 10 minu tes, but also greatly improve the refining of kaolin. When the complexes are hea ted to 120 ℃, the gas they send out can further delaminate kaolin. In this way, the authors can get the refined kaolin whose grain size is -2　μm>90%, and the lamellar crystal is perfect. This technology offers an innovational thinking and a method for preparing “double 90” refine kaolin.

With the rising of the pH value, the amount of fluorin e adsorbed by montmorillonite decreases rapidly and, what is worse, montmorillon ite seems almost not to absorb fluorine ions at all in basic-neutral solution.

The results show that the main sp ecies of Qingtian stone is of pyrophyllite type. Nevertheless, there also exist some other types, such as dickite-type, illite-type and sericite-type. This pape r has discussed mineral composition, gem features and formation mechanism of the Qingtian stone.

The Tertiary basalt in the Jiyang De pression can be divided into tholeiite and alkali two series. The alkali series basalt was mainly agpaitic series, and the Tertiary basaltic magmatite of this a rea whose eruptive depth was 150～230km was mainly continental tholeiite of cont i nental rift genesis. During the forming process of magma, mixing reaction happen ed among different source area, and melting degree decreased gradually from the Paleocene to the Oligcene, which suggested that the mantle source depth of magma increased gradually. These cognitions will of important reference significance to hydrocarbon exploration in magmatic rock.

Study of petrology of quartz monzonites from Dashui area suggests that the Zh onggezhala, Zhongqu and Ge'erkuohe bodies are derived from a comagmatic region. Although their crystallization temperature of about 700 ℃～800 ℃ is ex actly alike, the emplacement depth among them is very different, from 20 km～22 km of Zhonggezhala through 16 km of Zhongqu to 8 km～11 km of Ge'erkuohe towards the east. Moreover, the later two bodies show a signature of subvolcanic rock. This implies that hypabyssal magma is beneficial to the gold mineralization in t he Dashui area. This is why the large-scale gold deposit was defined in the vici nity of Ge'erkuohe and Zhongqu bodies, but only ore spot was found nearby Zhongg ezhala body.

Nd isotopic characteristics of rocks suggest that the granite resulted from t he mixing of the crust material with the mantle material, and that the mantle ma terial derived from the deep source got into and was distributed unevenly in the granite body. The mantle material might have mainly taken the form of mantle fl uid to join the process of granitic evolution. Under the Mesozoic background of lithosphere thinning in East China, the mantle fluid underplating induced the re melting of Meosoproterozoic strata, forming granitic magma.

There are two types of adakites with different petrogen esis: one is formed by the melting of subducting young slab, and the other is fo rmed by the partially melting of basaltic lower crust under the continental accr etion setting. Adakites are important indicators of ore deposits.

The analysis on the reef encountered during the drilling shows that the calcilute mound is mainly formed in continent al shelf and inner zone of the shelf margin, while framework reef and baffle ree f are mainly in the shelf and the shelf margin.

Dongying-Huimin sag is located in the south of Jiyang Depression of the Bohai wan Basin. Commercial oil has been found in the Palaeocene and Lower Eocene Kong dian Formation. Hydrocarbon potential of Kongdian Formation is closely related t o the Early Tertiary basin prototype that controlled formation of oil and gas re servoirs. The prototype basin in that period was recognized as an extending half graben that was faulted in the north and onlapped in the south based on analysi s of tectonic evolution and sedimentary facies. The major controlling faults inc luded the north-northeast struck Ningnan fault, the western part of Wunan fault and Chennan fault. The Sichuan fault, the east part of Chennan fault and Wunan f ault that struck to northwest have also played a great part.

The high-resolution sequence stratigraphical framework of Sha-3 member in the central sag of Dongying Depression has been established based on study of drill ing data and seismic data. The middle member of Sha-3 can be divided into one lo ng-term and six short-term of base level cycles. In accordance with the characte ristics of the base levels and the forming mechanism of the sandbody, the lithol ogic traps can be divided into three types: slump turbidite trap, slope-moving t urbidity fan trap and sublacustrine fan trap. The formation of traps was related to the evolution of base levels. The sub-lacustrine fan and slope-moving turbid ity fan which consisted of the main reservoirs were formed during rising stage o f the base level, and the slump turbidite was formed during the falling of base level.
