The deposit is confined within a felsic tuff unit; about 10 meters thick where sampled for chemical analysis. Using XRF, EDS and XRD techniques, we found besides todorokite, cryptomelane, quartz, romanechite (psilomelane), birnessite, illite-muscovite, cristobalite, chlorite, barite, halloysite, woodruffite, nacrite or kaolinite, and possibly hollandite-ferrian, as well as an amorphous material and two unknown manganese phases.

The quadrangle spans much of the Nashoba terrane and a small area of the Avalon terrane. Two stratigraphic units were defined in the Nashoba terrane: the Cambrian to Ordovician Marlboro Formation and the Ordovician Nashoba Formation. In addition, four igneous units were defined in the Nashoba terrane: the Silurian to Ordovician phases of the Andover Granite, the Silurian to Devonian Assabet Quartz Diorite, the Silurian to Devonian White Pond Diorites (new name), and the Mississippian Indian Head Hill Igneous Complex. In the Avalon terrane, one stratigraphic unit was defined as the Proterozoic Z Westboro Formation Mylonites, and one igneous unit was defined as the Proterozoic Z to Devonian Sudbury Valley Igneous Complex. Two major faults were identified: the intra-terrane Assabet River fault zone in the central part of the quadrangle, and the south-east Nashoba terrane bounding Bloody Bluff fault zone.

    PART file:///C:/DOCUME~1/ROBERT~1/Desktop/Z1010F~1/FINALS~1.HTM CHAPTER 10 MOLLUSCS 10.1 A Significant Space A. Evolved a fluid-filled space within the mesoderm, the coelom B. Efficient hydrostatic skeleton; room for networks of blood vessels, the alimentary canal, and associated organs. 10.2 Characteristics A. Phylum Mollusca 1. Contains nearly 75,000 living species and 35,000 fossil species. 2. They have a soft body. 3. They include chitons, tooth shells, snails, slugs, nudibranchs, sea butterflies, clams, mussels, oysters, squids, octopuses and nautiluses (Figure 10.1A-E). 4. Some may weigh 450 kg and some grow to 18 m long, but 80% are under 5 centimeters in size. 5. Shell collecting is a popular pastime. 6. Classes: Gastropoda (snails…), Bivalvia (clams, oysters…), Polyplacophora (chitons), Cephalopoda (squids, nautiluses, octopuses), Monoplacophora, Scaphopoda, Caudofoveata, and Solenogastres. B. Ecological Relationships 1. Molluscs are found from the tropics to the polar seas. 2. Most live in the sea as bottom feeders, burrowers, borers, grazers, carnivores, predators and filter feeders. 1. Fossil evidence indicates molluscs evolved in the sea; most have remained marine. 2. Some bivalves and gastropods moved to brackish and fresh water. 3. Only snails (gastropods) have successfully invaded the land; they are limited to moist, sheltered habitats with calcium in the soil. C. Economic Importance 1. Culturing of pearls and pearl buttons is an important industry. 2. Burrowing shipworms destroy wooden ships and wharves. 3. Snails and slugs are garden pests; some snails are intermediate hosts for parasites. D. Position in Animal Kingdom (see Inset, page 172) E.

While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

  • Fracture Characterization Mapping for Regional Geologic Studies: the Hydrostructural Domain Approach, Ayer Quadrangle, Massachusetts
    Fracture Characterization Mapping for Regional Geologic Studies: The Hydrostructural Domain Approach, Ayer Quadrangle, Massachusetts Stephen B. Mabee And Joseph P. Kopera Office of the Massachusetts State Geologist Geosciences Department University of Massachusetts 611 North Pleasant Street Amherst, MA 01003 Abstract While traditional bedrock geologic maps contain valuable information, they commonly lack data on brittle fracture characteristics and distributions. The increased need for better understanding of groundwater flow behavior in bedrock aquifers has made this data critical. The concept of hydrostructural domains is used to redefine bedrock mapping units based on an assemblage of lithologic and fracture characteristics thought to be important controls on groundwater flow and recharge. These maps are constructed from detailed field observations and measurements of 2000-3000 fractures from 60-70 stations across a 7.5' quadrangle. Hydrostructural domains are displayed on the map as traditional lithologic units would be, with detailed descriptions and photos of the fracture systems contained in each hydrostructural “unit”. In the Ayer quadrangle, such domains closely correspond with bedrock lithology and ductile structural history. Steeply dipping metasedimentary rocks of the Merrimack Belt have pervasive, closely spaced, throughgoing fractures developed parallel to foliation, and therefore may provide excellent potential for vertical recharge and foliation-parallel flow. Where these rocks are intensely cut by a strong subhorizontal cleavage, a parallel fracture set dominates providing an opportunity for lateral flow. Massive granites generally have a well-developed, widely-spaced orthogonal network of fracture zones which may provide excellent local recharge. High-grade gneisses of the Nashoba formation have poorly developed fracture sets except near regional shear zones, where foliation parallel fractures and cross-joints may provide good vertical recharge and provide a strong northeast trending flow anisotropy.
