Geology (from Greek γη- (ge-, "the earth") and λογος (logos, "word", "reason")) is the science and study of the solid matter of the Earth, its composition, structure, physical properties, history and the processes that shape it.
The word "geology" was first used by Jean-André Deluc in the year 1778 and introduced as a fixed term by Horace-Bénédict de Saussure in the year 1779.
In geology, when an igneous intrusion cuts across a formation of sedimentary rock, it can be determined that the igneous intrusion is younger than the sedimentary rock.

The Fergana intermontane depression of the Tyan-Shan orogen of Central Asia measures 350 by 130 km, and the area within it that is favorable for petroleum discovery covers 34,100 sq km.
The central part of the depression is characterized by block subsidence to depths of 6-7 km.
In the Fergana depression most of the discoveries have been small, but there are possibilities for discovery of larger fields as suggested by recent discovery of Mingbulak and Severo-Karakchikum-Niyabek in the Central Mega-Syncline (See Abidov and others, 1992, digested in Petroleum Geology, vol.

 Yale University - Department of Geology and Geophysics
His identification of the need for the broad depression of the Pacific sea floor to accommodate the upward growth of coral reefs to form the fringing reefs and atolls of the Pacific was a unique insight of Dana's and contributed to his grand view.
Although James Dwight Dana wrote several texts addressing the major problems of geology in the nineteenth century, not until the twentieth century was the primacy of Yale as the tutor to the nation in geology established.
The historical geology text was being transformed from being written by Charles Schuchert and Carl O. Dunbar to sole authorship by Dunbar since Schuchert had died many years earlier.

Depression in varying degrees affects up to 5 percent of all elderly.
Some researchers believe the percentage is greater, that some elderly patients diagnosed with dementia may actually suffer from depression that, if treated, is reversible.
Depression in the elderly is frequently dismissed as simply "part of growing old." It is not, and in serious cases it can pose a significant health hazard in the elderly by exacerbating existing physical problems or boosting the risk of suicide.

 NMBGMR Circular 106   (Site not responding. Last check: 2007-10-22)
The theoretical aspects of sulfide depression by permanganate oxidation have been discussed and this study investigated the oxidizing characteristics of permanganate on actual flotation-plant concentrates by comparing it with two other oxidizers used in the selective flotation of molybdenite.
The study shows that the effectiveness of these reagents in the depression of copper sulfide minerals is affected by reagent concentration, pH, temperature, and conditioning time.
Potassium permanganate shows improved depression at higher concentrations, whereas the others do not, possibly because of the formation of a mineral surface coating by colloidal MnO2 that inhibits any further xanthate action.
