The Shanxi and Taiyuan formations in Permo-Carboniferous of upper Paleozoic Erathem of Qinshui Basin, not only has abundant coal and CBM resources, also has a lot of shales. By analyzing the shale thickness, organic matter type, organic matter abundance, vitrinite reflectance, mineral composition of the Permo-Carboniferous coal-bearing strata, considered that the shale thickness of coal-bearing strata in the Qinshui Basin is larger, the organic matter abundance is general, but maturity is high and full of rich brittle mineral. It is in favor of late fracturing.

Gulong depression is one of the inheritance deposition and subsidence center, also is the most developed secondary structural belt in Songliao Basin. In this research area, the total organic carbon TOC content of the shale in Qingshankou Formation is mainly more than 1%. The organic matter of the shale in Qingshankou Formation has better types, typeIis major and followed by typeII. The maturity of the source rock in Qingshankou Formation of Gulong area is greater than 0.7%, and up to 1.8%, mainly in the mature-high mature stage. Since the shale of Qingshankou Formation has the features of great thickness, higher organic matter abundance, better type and mature-high mature stage, also it is located in the junction between lake facies and delta front facies with better brittle mineral content, so its the key area of the exploration of shale oil. In this text, find the areas which is S1 is more than 2 mg/g and the brittle mineral (quartz and feldspar) content is more than 50% in Gulong depression, and this areas are consistent with the distribution of industrial oil wells and low yield industrial oil wells in research area. This text provides a fast and effective method for the exploration and development of oil shale.

The Qingshankou and Nenjiang group in upper cretaceous of Songliao basin is a set of dark shale. Analyze the shale thickness, organic matter type, organic matter abundance, vitrinite reflectance, mineral composition of the permo-carboniferous coal-bearing strata. Consider that the thickness of shale in the Songliao basin is larger, despite the organic matter abundance is good, but maturity is lower, less of the formation of oil and gas.

Sungai Jajar merupakan salah satu sungai besar yang aliran sungainya banyak dimanfaatkan penduduk sekitar. Kondisi ini akan berdampak terhadap kualitas perairan yang dapat mengakibatkan suatu pencemaran. Makrozoobentos merupakan hewan yang hidup di dasar perairan dan dapat dijadikan sebagai bioindikator karena habitat hidupnya relatif menetap. Tujuan dari penelitian ini adalah untuk mengetahui tekstur sedimen, kandungan bahan organik, kelimpahan makrozoobentos, hubungan tekstur sedimen dengan bahan organik; tekstur sedimen dengan kelimpahan makrozoobenthos; dan hubungan bahan organik dengan kelimpahan makrozoobenthos. Penelitian dilaksanakan pada bulan Maret-April 2018 menggunakan teknik purposive random sampling dengan total 6 stasiun. Sampel yang diambil adalah substrat dan makrozoobenthos. Hasil penelitian menyatakan bahwa nilai fraksi sand berkisar antara 3,66 -8,40%; fraksi silt berkisar antara 1,29-1,80% dan fraksi clay berkisar antara 89,89-94,81%. Jenis makrozoobentos yang ditemukan dikelompokkan dalam 3 kelas, yaitu: Gastropoda (Cerithidea sp, Terebra sp, Pila sp, Murex sp, Urosalpinx sp, Filopaludina sp dan Telescopium sp), Bivalvia (Anadara sp, Mesodesma sp, Mytillus sp) dan Polychaeta (Nereis sp). Kelimpahan individu berkisar antara 280-2320 ind/m2 dengan kelimpahan tertinggi terdapat pada stasiun III dan kelimpahan terendah pada stasiun I. Kandungan bahan organik berkisar antara 6,73-9,4 %. Hubungan bahan organik dengan tekstur sedimen memiliki korelasi yang cukup erat. Hubungan antara tesktur sedimen dengan kelimpahan makrozoobenthos memiliki korelasi yang rendah. Hubungan bahan organik dengan kelimpahan makrozoobenthos menunjukkan hubungan yang cukup erat dengan nilai koefisien korelasi sebesar 0,557.                 Sungai Jajar is one of the major rivers where the river flows are widely used by local people. This condition will have an impact on water quality which can cause a pollution. Macrozoobenthos are organism that live in the bottom of the water and can be used as bioindicators because their habitat is relatively sedentary. The purpose of this study was to determine sediment texture, organic matter, abundance of macrozoobenthos, sediment textures relationship with abundance of macrozoobenthos; relationship of organic matter with sediment texture; and the relationship of organic matter with abundance of macrozoobenthos. The study was conducted in March-April 2018 using purposive random sampling method technique with a total of 6 stations. The samples taken were substrate and makrozoobenthos. The result refers that sand fraction value ranged from 3,66%-8,40%; Silt fraction ranged from 1,29%-1,80% and clay fraction ranged from 89,89%-94,81%. Macrozoobenthos found in three classes are: Gastropods (Cerithidea sp, Terebra sp, Pila sp, Murex sp, Urosalpinx sp, Filopaludina sp and Telescopium sp), Bivalvia (Anadara sp, Mesodesma sp, Mytillus sp) and Polychaeta (Nereis sp). Individual abundance ranged from 280-2320 ind/m2 with the highest abundance found at station III and the lowest abundance at station I.  The content of organic material ranges from 6,73% -9,4%. The relationship of organic matter with sediment texture has moderate correlation. The relationship between sediment texture and abundance of macrozoobenthos has low correlation. The relationship of organic matter with abundance of makrozoobenthos shows a fairly strong relationship with a correlation coefficient of 0,557.
