Among the three major types of rock, fossils are most commonly found in sedimentary rock. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remnants.ost sedimentary rocks contain either quartz (especially siliciclastic rocks) or calcite (especially carbonate rocks). In contrast to igneous and metamorphic rocks, a sedimentary rock usually contains very few different major minerals.
How many tons for a 1500 sq ft home. I have been getting bids for an ac unit in my home and I have been getting a range of 3 tons to 3.5 tons. I live in Dallas Texas and my home is pretty well shaded during the days and the majority of my windows face north or south.
For simplicity, lets say your 1500 sq. ft. house is 15 ft. by 100 ft. Lets say the height of your exterior walls is 10 ft. You have two long walls 100 ft. long times 10 ft. tall or 1000 sq. ft. of facing area, and two short walls 15 ft. wide times 10 ft. tall or 150 sq. ft. Adding all that up you end up with (1000x2)+(150x2)=2300 sq. ft. of exterior wall that you need to cover with bricks.
