Georgian drift. The crisis of Georgia's way westwards. OSW POINT OF VIEW 57, 2016-02-22

For several years Georgia has been experiencing processes which may be interpreted as symptoms of a deepening, multidimensional social and political crisis. Reforms have lost momentum, stagnation has set in, and in some areas the situation has begun to revert to the pre-revolution status (including rising crime levels). The Georgian political system has found itself in a serious crisis, while society has become increasingly frustrated and apathetic, mainly because people’s standards of living have been stagnating. This political and social malaise has been breeding Euro-scepticism and disenchantment with the West. A country that had been firmly navigating westwards, Georgia has now started drifting and slipping into malaise. This risks reversing what the country has achieved so far in the internal dimension, increasing instability and triggering a crisis in the pro-Western vector of Tbilisi’s foreign policy. While that may not necessarily mean a turn towards Russia, in the present situation it has been easier for Moscow to pursue its own interests in the region. Should Tbilisi’s pro-Western course become reversed or permanently stagnant, that would entail grave consequences for the country itself and beyond. It would be a defeat for the West and would undermine the European aspirations of countries like Ukraine or Moldova.

Organic geochemistry of sediments at DSDP Legs 56-57 Holes

The quantity, type, and maturity of the organic matter of Quaternary and Tertiary sediments from the Japan Trench (DSDP Leg 56, Sites 434 and 436; and Leg 57, Sites 438, 439 and 440) were determined. The hydrocarbons in lipid extracts were analyzed by capillary- column gas chromatography and combined gas chromatography/ mass spectrometry. Kerogen concentrates were investigated by microscopy, and vitrinite-reflectance values were determined. Measured organic-carbon values were in the range of 0.13 to 1.00 per cent. Extract yields, however, were extremely low. Normalized to organic carbon, total extracts ranged from 4.1 to 15.7 mg/g Corg. Gas chromatography of non-aromatic hydrocarbons showed that all sediments, except one Oligocene sample, contained very immature, mainly terrigenous organic material. This was indicated by n-alkane maxima at C29 and C31 and high odd-carbon-number predominances. Unsaturated steroid hydrocarbons were found to be major cyclic compounds in lower- and middle-Miocene samples from the upper inner trench slope (Sites 438 and 439). Perylene was the dominating aromatic hydrocarbon in all but the Oligocene sample. Microscopy showed kerogens rich in terrigenous organic particles, with a major portion of recycled vitrinite. Nevertheless, almost all the liptinite particles appeared to be primary. This is a paradox, as the bulk of the samples were composed of hemipelagic mineral matter with a major siliceous biogenic (planktonic) component. A trend of reduced size and increased roundness can be seen for the vitrinite/ inertinite particles from west to east (from upper inner trench slope to outer trench slope). All sediments but one are relatively immature, with mean huminite-reflectance values (Ro)in the range of 0.30 to 0.45 per cent. The oldest and deepest sediment investigated, an Oligocene sandstone from Site 439, yielded a mean vitrinitereflectance value of 0.74 per cent and a mature n-alkane distribution. This sample may indicate a geothermal event in late Oligocene time. It failed to affect the overlying lower Miocene and may have been caused by an intrusion. Boulders of acidic igneous rocks in the Oligocene can be interpreted as witnesses of nearby volcanic activity accompanied by intrusions.
