Bedrock Geologic Map of the Cavendish Quadrangle, Vermont

Digital Data from VG95-203A Ratcliffe, NM, 1995,�Digital bedrock geologic map of the Cavendish quadrangle, Vermont: USGS Open-File Report 95-203, 2 plates, scale 1:24000. The bedrock geologic map data at a scale of 1:24,000 depicts types of bedrock underlying unconsolidated materials in Vermont. Data is created by mapping on the ground using standard geologic pace and compass techniques and/or GPS on a USGS 1:24000 topographic base map. Data may be organized by town, quadrangle or watershed. Each data bundle may includes point, line and polygon data and some or all of the following: 1) contacts (lithogic contacts), 2) fault_brittle, 3) fault_ductile, 4) fault_thrust, 5) fault_bed_plane (bedding plane thrust), 6) bedding, 7) bedding_graded (graded bedding) 8) bedding_overturn (overturned bedding), 9) bedding_select (selected points for published map), 10) foliation_n1, n2, n3 etc (foliation data), 11) outcrop (exposed outcrops), 12) field_station (outcrop and data collection point), 13) fold_axis, 14) axial_plane, 15) lamprophyre, 16) water_well_log (water well driller information), 16) linear_int (intersection lineation), 17) linear_str (stretching lineation) 18) x_section_line (line of cross-section), and photolinear (lineaments identified from air photos). Other feature classes may be included with each data bundle. (https://dec.vermont.gov/geological-survey/publication-gis/ofr).

VG95-203A 数字数据（来自新墨西哥州拉特克利夫，1995年）：佛蒙特州卡文迪什图幅数字基岩地质图——美国地质调查局（USGS）公开文件报告95-203，共2幅图件，比例尺1:24000。
该比例尺为1:24000的基岩地质图数据，展示了佛蒙特州未固结沉积物之下的基岩类型。本数据通过基于美国地质调查局（USGS）1:24000比例尺地形底图，采用标准地质步测、罗盘技术及/或全球定位系统（GPS）开展野外填图获取。数据可按城镇、图幅或流域进行组织分类。每个数据集包可包含点、线、多边形三类矢量数据，以及下述部分或全部要素：1）接触界线（岩性接触界线）；2）脆性断裂；3）韧性断裂；4）逆冲断层；5）层理面逆冲断层；6）层理；7）粒序层理；8）倒转层理；9）发布地图所用的选定点层理数据；10）叶理n1、n2、n3等（叶理数据）；11）露头（裸露露头）；12）野外测点（露头与数据采集点）；13）褶皱轴；14）轴面；15）煌斑岩；16）水井测井资料（钻井施工方信息）；16）线性交线理（交切线理）；17）线性拉伸线理（拉伸线理）；18）剖面线（横剖面线）；以及影像线性构造（通过航空照片识别的线性构造）。每个数据集包还可包含其他要素类。(https://dec.vermont.gov/geological-survey/publication-gis/ofr).
