Bedrock Geology Glossary from the Roadside Geology of Minnesota, Richard W
Minnesota Bedrock Geology Glossary From the Roadside Geology of Minnesota, Richard W. Ojakangas Sedimentary Rock Types in Minnesota Rocks that formed from the consolidation of loose sediment Conglomerate: A coarse-grained sedimentary rock composed of pebbles, cobbles, or boul- ders set in a fine-grained matrix of silt and sand. Dolostone: A sedimentary rock composed of the mineral dolomite, a calcium magnesium car- bonate. Graywacke: A sedimentary rock made primarily of mud and sand, often deposited by turbidi- ty currents. Iron-formation: A thinly bedded sedimentary rock containing more than 15 percent iron. Limestone: A sedimentary rock composed of calcium carbonate. Mudstone: A sedimentary rock composed of mud. Sandstone: A sedimentary rock made primarily of sand. Shale: A deposit of clay, silt, or mud solidified into more or less a solid rock. Siltstone: A sedimentary rock made primarily of sand. Igneous and Volcanic Rock Types in Minnesota Rocks that solidified from cooling of molten magma Basalt: A black or dark grey volcanic rock that consists mainly of microscopic crystals of pla- gioclase feldspar, pyroxene, and perhaps olivine. Diorite: A plutonic igneous rock intermediate in composition between granite and gabbro. Gabbro: A dark igneous rock consisting mainly of plagioclase and pyroxene in crystals large enough to see with a simple magnifier. Gabbro has the same composition as basalt but contains much larger mineral grains because it cooled at depth over a longer period of time. Granite: An igneous rock composed mostly of orthoclase feldspar and quartz in grains large enough to see without using a magnifier. Most granites also contain mica and amphibole Rhyolite: A felsic (light-colored) volcanic rock, the extrusive equivalent of granite. -

Direct contact with it is immediately injurious to skin, eyes, intestinal tract and respiratory system.) WHERE DOES CALCIUM CARBONATE COME FROM? Calcium carbonate can be mined from the earth in solid form or it may be extracted from seawater or other brines by industrial processes. Natural shells, bones and chalk are composed predominantly of calcium carbonate. WHAT ARE THE PRINCIPLE USES OF CALCIUM CARBONATE? Calcium carbonate is an important ingredient of many household products. It is used as a whitening agent in paints, soaps, art products, paper, polishes, putty products and cement. It is used as a filler and whitener in many cosmetic products including mouth washes, creams, pastes, powders and lotions. -

Part of this “anthropogenic CO2” invades the oceans causing a decrease of seawater pH; this process is called “ocean acidification.” The lowered pH, but also the concomitant changes in other properties of the carbonate system, affects marine life and the cycling of carbon in the ocean.

A Study of Lime and Fly Ash with Regard to Soil Stabilization

MEMO TO: D. V. Terrell Director of Research The attached report, "A Study of the Use of a Local Fly Ash in Concrete Mixes", by Frank D. Whitney, represents two approaches to the addition of fly ash to portland cement concrete. Certain percentages of cement were replaced with the fly ash for one series of inve sti.gations and for the other the cement content wa.s kept constant and the fly ash was used to replace sand. It was found that 25% of the cement could be replaced with the fly ash without detrimental losses, to the 28- and 60-day compressive strengths.· The 7-day strengths were lowered for the cement replacement tests. This report outlines procedures that are required to obtain durable concrete while replacing either 25% of the sand or 25% of the cement with fly ash, depending upon the particular economic situation or shortage of materiaL The findings here reported may be of considerable value to the department, especially if materia\ shortages should develop.
