Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

Hypogene high thermal or deep source epi-mesothermal condition and it is not only stressed the mantle source simply but also the crust-mantle;②in order to guid ore exploration better the artificial classification of uranium deposits should be broken and uranium ore-forming system strengthened;③much attention should be paid to searching the diabase-hosted rich uranium ore in strongly argillized cataclastic zone;④attention should be paid to the influence of basement of volcanic basin on the uranium ore formation that should be undstood both in feeling and theoretically through the ore propect process;⑤relation of red basin with uranium ore formation can be made clear from analyzing tectonics, paleo-climate and time and it is not only theoretically important but also helpful to uranium ore prediction;⑥crypto explosive pipe is an uranium ore, rich uranium ore host structure and it is the next goal for uranium ore exploration in east China.

Mr Thompson's approach deals summarily with geology, Herdwick sheep, mining and the Celts and Norse-Irish who bequeathed many of the place names to the eight valleys that, according to Wordsworth's description, radiate "from the nave of a wheel", a nub of rock formed by volcanoes as powerful as Vesuvius.

The Paleoproterozoic Beidahe Group-complex remains as continental shivers in the interior of the North Qilian orogen. In its early stage of development, there occurred abundant amphibolite. The protolith of the amphibolite is basalts. The Alk-∑FeO-MgO plot, REE features and Rittmann index show that the protolith belongs to the calc-alkaline suite and exceptionally shows the subalkaline character. The rock is characterized by higher Al2O3 and ∑FeO and lower Mg#, indicating that it has a higher degree of compositional evolution and that the formation of volcanic rocks is related to activation of older crust. Highly fractionated REE patterns and amphibolite on the Ti-Zr-Y plot, Ni-FeO/MgO plot and Ta/Yb-Th/Yb plot all indicate the characteristics of volcanic arcs and active continental margins. On the geochemical diagram of basalt, the overall REE features are in the main analogous to those of calc-alkaline island-arc basalt, with Sr87/Sr86=0.71617–0.72033,Nd143/Nd144=0.512414–0.512495 and εNd=–2.79 to –4.37,εSr=245.78–305.3, showing that the magma was derived from the crust or subjected to contamination with the lower crust below the continent.

The investigations into this remote area were difficult and the findings yielded many interesting theories, ranging from fairly plausible ideas about the arrival of a stony asteroid or comet, to more exotic hypotheses involving black holes, antimatter, mirror matter, volcanoes, ball lightning, and "geometeors," to really bizarre notions about crippled alien spaceships, laser beams from other planets and death rays secretly invented by Nikola Tesla.
