These are known as contour lines. FREE topographic maps online 24/7. Contour lines connect points of equal elevation. If this is the case, it is a good idea to note where actual well control points are so that one can keep in mind which fault blocks have actual well control. Topographic map coverage of Canada is based on the National Topographic System (NTS). These maps depict in detail ground relief (landforms and terrain), drainage (lakes and rivers), forest cover, administrative areas, populated areas, transportation routes and facilities (including roads and railways), and other man-made features. Take data points and make a contour map-more complex than fault map because more structures Now find trace-line where to intersect;-overlay map 1 on map 2-look for points of equal elevation on both fault and horizon maps-mark off two points, this will give you the trace of the fault folds, are represented in three dimensions. ... while the bank looks to be an uninteresting gravel bank, below water there are some structural features that have bass attracting appeal. A map on which structural features, e.g. Topographic Map Basics. A A,C B B C The contours are based on a single horizon (e.g. As confirmation, note that contacts nearly parallel the elevation contours near the map center. We recognize three major tectonic zones that correspond closely to Precambrian-basement structures and/or terrane boundaries. the top of a bed), the position of that horizon being given with reference to a datum plane. Interpretations of depositional trends, pre-and syndepositional structural development, and reservoir storage capacity are based in large part on thickness information. 200m Structure contour 200m Fig. Contour Maps - They're About Finding Underwater Structures. Structure Contour Maps Structure Contour Maps Structure Contour Maps Structure Contour Maps A contour that connects points of equal thickness. Geology is a very visual science, and the use of a variety of map types is common. Sometimes. Also, line AB on the map cuts into the layer, whereas AC does not: AC is the strike. Commonly, the isopachs, or contours that make up an isopach map, display the stratigraphic thickness of a rock unit as opposed to the true vertical thickness. With less well control, seismic mapping is often incorporated into the structure mapping so the actual structural contour map is a composite of both. Return to Fishing and Lake Maps from Contour Maps. A breakline, a pinch point on that breakline and a creek bed. The Bighorn Basin is a large intermontane sedimentary and structural basin that formed during the Laramide orogeny. This lesson will differentiate between three types of geologic maps: topographic, cross-sectional, and structural. View all of our high-quality shaded relief USGS topo maps, Forest Service maps, satellite images, and custom map layers for free. The first commercial hydrocarbon production in the Bighorn Basin was established in 1906 from Cretaceous reservoirs at Garland field followed by the discovery of Greybull field in 1907. The resulting six structural contour maps add to our understanding of the tectonic development of Kansas and suggest the complexity to be expected in neighboring areas. The map is read in the same way as a topographic contour map. We begin our focus on the basic part of a topographic map, all those lines. An accurate meaning of thickness is critical in these and other analyses (see Conversion of well log data to subsurface stratigraphic and structural information).. Isopach.
