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. -

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. -
Petrology of the High-Alumina Hoosac Schist from the Chloritoid+Garnet Through the Kyanite+Biotite Zones in Western Massachusetts1
332 PETROLOGY OF THE HIGH-ALUMINA HOOSAC SCHIST FROM THE CHLORITOID+GARNET THROUGH THE KYANITE+BIOTITE ZONES IN WESTERN MASSACHUSETTS1 by John T. Cheney, Department of Geology, Amherst College, Amherst, MA 01002 and John B. Brady, Department of Geology, Smith College, Northampton, MA 01063 INTRODUCTION The eastern limb of the Berkshire anticlinorium of western Massachusetts (Figure 1) is a complex, multiply- deformed, polymetamorphic, Taconian/Acadian orogenic terrane. The geologic framework of this area is well established, originally by the mapping of B.K. Emerson (1892, 1898, 1899) and Pumpelly et al. (1894), as summarized on the Massachusetts geologic map of Emerson (1917), and more recently by the mapping of L.M. Hall, N.L. Hatch, S.A. Norton, P.H. Osberg, N.M. Ratcliffe, and R.S. Stanley, as summarized on the Massachusetts geologic map of Zen et al. (1983). The summary reports of USGS Professional Paper 1366 in 1988 as well as the work of Hatch et al. (1984), Stanley and Ratcliffe (1985), and Sutter et al. (1985), among others, provide a provocative regional synthesis that brings into sharp focus a variety of interrelated structural, stratigraphic, petrologic, and geochronologic problems. Despite vigorous efforts, our ability to constrain the timing of many fundamental events is still hampered by both the complexity of the terrane and a lack of data. As reviewed by Karabinos and Laird (1988), differentiating between the effects of different metamorphic events remains quite problematic in much of the terrane. The recent work of Hames et al. (1991) and Armstrong et al. (1992) emphasizes the problem of differentiating between Taconian and Acadian orogenic effects along the zone of maximum overlap, which generally coincides with the axis of the Berkshire massif. -

Appendix 4 LCESS Technology Information
Appendix 4: Additional Technical Information 1. Geothermal Potential of Cambridge In order to understand the geothermal potential of the aquifers below the city it was necessary to assess the Geology. Cambridge is located in the Milford-Dedham Zone and specifically in the Boston Basin (Figure 1). The geology of the Boston basin consists of Cambridge Argillite (PrZc), Roxbury Conglomerate (PrZr) and Melaphyre (volcanic deposits, related to basalt) which is part of the Roxbury Conglomerate. A cross section just North of Cambridge is shown in Figure 2. The figure shows that underlying the Roxbury Conglomerate, the Mattapan Volcanic Complex (Zm) and the Dedham Granite (Zdngr) are found. Deep Geothermal To investigate the deep geothermal (>1km depth) potential of the aquifers below the city Ramboll contacted the University of Massachusetts and the Geological Energy Systems dept. at the University of Glasgow, Scotland (which shares a geological history with Massachusetts). The University of Massachusetts conducted the Massachusetts Geothermal Data Project, which has produced maps outlining the geothermal potential of the existing aquifers in the state. Based on the work they have done, the argillites in the Cambridge Basin are not an obvious deep geothermal target, and are currently not on their list of potential Massachusetts targets (even when considering low temperature requirements of around 140⁰F/60⁰C).

B2-1 124 BOSTON BASIN RESTUDIED Clifford A. Kaye U.S. Geological Survey (retired) 150 Causeway Street, Suite 1001 Boston, MA 02114 Abstract Recent mapping of the Boston Basin has shown that the sedimentary and rhyolitic and andesitic volcanic rocks are interbedded and that all lithic types interfinger, reflecting a wide range of depositional environments, including: alluvial, fluviatile, lacustrine, lagoonal, and marine-shelf. In addition to the well-known sedimentary rocks, such as argillite and conglomerate, we now recognize calcareous argillites, gypsiferous argillites of hypersaline origin, black argillite, red beds, turbidity current deposits, and alluvial fan deposits. The depositional setting seems to have been a tectonically active, block-faulted terrane in a coastal area. The granites that underlie these rocks are approximately the same age, some of them intruding the lower part of the sedimentary and volcanic section and feeding the rhyolitic Volcanics within the section. All of this took place in Late Proterozoic Z-Cambrian time. -
