	abstract = {Despite the state{\textquoteright}s relatively high population density and decades of detailed study of the bedrock geology, only about half of the 7.5{\textquoteright} quadrangles in Massachusetts have been published as GQ series geologic maps. As the state{\textquoteright}s population continues to grow, the availability of basic geologic data becomes increasingly crucial for informed land-use and water-management decision making. Much of the published 1:24000 scale geologic mapping predates recent advances in the understanding of regional tectonics, and needs to be updated. The Office of the State Geologist has begun a geologic mapping program in Massachusetts to address these needs. Two mapping projects were conducted through the STATEMAP component of the National Cooperative Geologic Mapping program in 2003. These projects focused on 7.5{\textquoteright} quadrangles along the I-495 corridor, which is experiencing extensive population growth and development. The first project involved conversion of published 1:24,000-scale surficial geology to digital form for 10 quadrangles in southeastern Massachusetts. A semi-automated process was developed for this project that easily converts published paper geologic maps into vectorized, georeferenced datalayers. The second project involved 1:24000-scale geologic mapping of the Marlborough quadrangle in east-central Massachusetts. Products include traditional maps of bedrock and surficial geology as well as two new prototype products: a fracture characterization map and a surficial materials map. These projects mark the first time in Massachusetts{\textquoteright} history that quadrangle-scale geologic data will be available in digital form to consultants and stakeholders, thus greatly expediting and improving the use and analysis of all geologic data. In addition, the inclusion of fracture characterization and surficial materials maps adds substantially to the value of traditional geologic map products. The new maps provide supplemental data on the hydrologic characteristics of the bedrock and the vertical stacking of surficial deposits that previously was unavailable. STATEMAP projects in 2004 will continue to focus along the I-495 corridor, and will involve revision and new mapping in the Wilmington, Reading, South Groveland, Lawrence, Hudson, and Oxford quadrangles.},

	abstract = {Three methods of fracture data collection are tested against each other in layered dolomitic rocks to evaluate the effectiveness of each method in sampling fracture properties. The methods tested are the single scanline method (SSM), selection method (SM), and multiple scanline method (MSM). Finite element techniques were first used to build a base model with the exact locations, sizes and orientations of each fracture observed in the natural fracture network. Then, a second set of models were stochastically generated using statistics from each sampling technique. For each network, the overall fracture intensity was used to assess the effectiveness of each sampling technique in capturing the real fracture properties. Fracture network permeability was also calculated for each of two directions to evaluate the transmissive properties of the networks. Although all three methods produced good matches of relative intensity and permeability between natural and synthetic fractures, the results reveal that a well-placed scanline performed the best at recreating natural fractures. However, the results from one variation of the SSM were only slightly better than the results from both versions of the SM. In general, the SSM provides the best results but possibly at heavy costs in time and labor, whereas the SM gives comparable results with less expenditure of energy and time. Thus, the SM is an adequate technique and recommended for use at large outcrops or where time, access or budget constraints are a concern.},
