Tectonic evolution and paleokarstification of carbonate rocks in the Paleozoic Tarim Basin
Thick carbonate rocks were developed in the depression of the Tarim craton during the Cambrian-Middle Ordovician periods. The compressional tectonic movement during the Middle Caledonian-Hercynian created the paleouplifts, which became the base for the paleokarst in the Ordovician carbonate rocks. Based on the large quantity of seismic, drilling, and geological outcrop data, this study analyzed...
متن کاملPhenylnaphthalenes and polyphenyls in Palaeozoic source rocks of the Holy Cross Mountains, Poland
Source rocks from a marine depositional setting from Palaeozoic formations in the Holy Cross Mountains region (Midlands, Poland) were analysed for aromatics using capillary gas chromatography±mass spectrometry (GC±MS). The occurrence of two novel series of aromatic hydrocarbons in these sediments, namely phenyl derivatives of fused ring polycyclic aromatic hydrocarbons (PhPAH) and polyphenyls (...
متن کاملDiscordant paleomagnetic direction in Miocene rocks from the central Tarim Basin: evidence for local deformation and inclination shallowing
From exposures at the southeastern end of the Maza Tagh range in the central Tarim Basin (latitude: 38.5‡N; longitude: 80.5‡E), 55 paleomagnetic sites were collected from red mudstones and sandstones of the Miocene Wuqia Formation. Thermal demagnetization revealed a high unblocking temperature characteristic remanent magnetization (ChRM). Five sites collected across a kink fold yield a positive...
متن کاملPaleozoic oil±source rock correlations in the Tarim basin, NW China
We studied a suite of 40 oils and extracts of purported source rocks from the Tarim basin in NW China. The main group of oils comes from Tazhong and Tabei wells, which sample the largest known petroleum accumulations in the basin. These oils can be statistically correlated with extracts of Ordovician rocks based upon high relative concentrations of 24-isopropylcholestanes and low relative conce...
متن کاملLower Palaeozoic Unconformities in South-western Tasmania
Recent geological work in south-west Tasmania on a regional scale has allowed the compilation of existing information regarding Lower Palaeozoic unconformities, namely the description of new localities and in some cases the amplification and extension of previously described exposures. Carey and Banks (1954, p. 245) provide a review of information to 1954 and their classification of unconformit...
