the compressive and tensile strength of rocks from indentation hardness index by S. Kahraman*‚ M. Fener†‚ and E. Kozman‡ Synopsis The prediction of rock properties from indirect testing methods is important‚ particularly for preliminary investigations since indirect tests are easier and cheaper than the direct tests. In this study‚ we investigate the predictability of the uniaxial compressive strength (UCS ) and Brazilian tensile strength (BTS ) of rocks from the indentation hardness index (IHI

Pangaea is the proposed supercontinent that 200 million years ago supposedly began to shift apart and form our present continents. Alfred Wegener proposed this theory along with continental drift; Evidence he used includes matching fossils‚ rock types‚ and ancient climates

The social and political context of the 1950’s is crucial to any understanding of the birth of rock n roll. "Rock was formed out of the social‚ economic and political context of post-war America". The social context was on the bases of the post war baby boom‚ which counted for the birth of 77 million babies between the years 1946-1964. By the year 1964 forty percent of America’s population was under twenty years of age. For the first time both middle and working class youths were acquiring an

ANDESITE: a dark‚ fine-grained‚ brown or grayish volcanic rock that is intermediate in composition between rhyolite and basalt. ANTHRACITE: coal of a hard variety that contains relatively pure carbon and burns with little flame and smoke.

Rock music of today has turned to shit because of MTV’s TRL‚ the billboards‚ and Brittney Spears’s record sales have something to do with the size of her breasts. Rock music from the 70’s through today will be remembered for years‚ but it lacks the true timelessness of classical music. Classical music has beautiful harmonies that be appreciated for thousands of years. Modern rock is a shallow reflection of the time‚ showing lack of development due to sell out bands making music for money and not

band in a Gneiss. An anticline occurs on a much larger scale. The both are affected by the same compressional stress. In an anticline the oldest rocks are exposed in the middle of the structure and get younger as you move out. They are likely to out crop especially if the syncline has a resistant layer. On a map you would look for an area with older rocks in the middle with younger units as you move outward. The difference between a synform and a syncline are the same as with the antiform and the

The Standing Rock Sioux Tribe and the environmentalist and local citizens raised high concerns about the potential health and environmental consequences of oil spills‚ because after many research’s pipelines always leak. The pipeline can contaminate the Missouri River‚ which supplies drinking water for millions of Americans households and irrigation supply for thousands of acres farming lands. The Native American tribe is concerned about the vicinity of the pipeline to their reservation. They are

Introduction Rose quartz is a pale pink to rose-red variety of quartz. Quartz is the second most plentiful mineral found in the Earth’s crust. Rose Quartz occurs only in massive formations‚ with no crystal faces‚ edges or points. It is often hazy or turbid; therefore it lacks good transparency. It also contains microscopic fibers‚ which can on occasion produce a cat’s eye or star effect within the stone. Rose quartz crystals are formed when the pressure within the earth pushes molten lava into
