March 2020 Meetings and Field Trips Cancelled Until Further Notice Due to Covid-19 Concerns Daisy Mountain Rockchips The purpose of Daisy Mountain Rock & Mineral Club is to promote and further an interest in geology, mineralogy, and lapidary arts, through education, field experiences, public service, and friendship. VOLUME 5, ISSUE 3 MARCH 2020 MEETINGS AND FIELD TRIPS CANCELLED UNTIL FURTHER NOTICE DUE TO COVID-19 CONCERNS A garden of corals in the now-buried (by lava) Kapoho Tidepools, Pahoa, Hawaii. This photo illustrates the colors missing from the fossil record. And it displays the potential growth forms -- many of which are related to the amount of turbulence in the water. Given species may be robust and massive in turbulent environments, and more delicately branching in quiet.

It is one of pens, jellyfish, box jellies, hydrozoa (which include four minerals composed of carbon, the others the Portuguese Man O’War), stalked jellyfish, and being: diamond, chaoite, and lonsdaleite. other lesser known groups and species. Of these, Diamond -- the hardest natural substance known by far the majority in the fossil record are the on Earth -- has the same composition (but different corals, because they include species that create a crystal structure) as Graphite -- one of the softest hard calcium carbonate structure; while the others natural substances. are largely soft-bodied with no hard parts. Chemical Formula - C (Carbon) The name, Cnidaria, is derived from knidē, which Crystal System - Hexagonal (4 axes -- 3 of equal is Greek for “nettle”.

  • CNIDARIA Corals, Medusae, Hydroids, Myxozoans
    FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell.

  • Geology of Michigan and the Great Lakes
    35133_Geo_Michigan_Cover.qxd 11/13/07 10:26 AM Page 1 “The Geology of Michigan and the Great Lakes” is written to augment any introductory earth science, environmental geology, geologic, or geographic course offering, and is designed to introduce students in Michigan and the Great Lakes to important regional geologic concepts and events. Although Michigan’s geologic past spans the Precambrian through the Holocene, much of the rock record, Pennsylvanian through Pliocene, is miss- ing. Glacial events during the Pleistocene removed these rocks. However, these same glacial events left behind a rich legacy of surficial deposits, various landscape features, lakes, and rivers. Michigan is one of the most scenic states in the nation, providing numerous recre- ational opportunities to inhabitants and visitors alike. Geology of the region has also played an important, and often controlling, role in the pattern of settlement and ongoing economic development of the state. Vital resources such as iron ore, copper, gypsum, salt, oil, and gas have greatly contributed to Michigan’s growth and industrial might. Ample supplies of high-quality water support a vibrant population and strong industrial base throughout the Great Lakes region. These water supplies are now becoming increasingly important in light of modern economic growth and population demands. This text introduces the student to the geology of Michigan and the Great Lakes region. It begins with the Precambrian basement terrains as they relate to plate tectonic events. It describes Paleozoic clastic and carbonate rocks, restricted basin salts, and Niagaran pinnacle reefs. Quaternary glacial events and the development of today’s modern landscapes are also discussed.
