Block diagram geology. The sequence begins with the folded metamorphicgneisson the bottom. Come look inside i then made the cretaceous block semi transparent so that i could view the base of the block and added oil reservoir accumulations again processed using the extrude between tool to place them at the base cretaceous trapped at the contact between the upper jurassic and the base cretaceous seal along fault footwall topography. It is like a block or chunk cut out of the earth. Stress force per unit area may deform or.

A block diagram shows the surface of the earth and also at least one cross section. Since a geologic map shows only the surface of the earth symbols must be used to show what the rocks are doing beneath the surface. 2 the sides of the block are vertical walls will show the dip direction of the beds will show the dip angle of the beds up to structural geology topic list. This diagram uses strike and dip of repeating rock units to produce a geologic map and to infer the underlying fold.

Principles are given in the following block diagrams figure 1. Later these beds were folded into an anticline. Sometime later a normal fault occurred. Switching on all block units displays a block diagram below right.

Notice the differential weathering of different rock layers especially on the right side of the image. For each diagram draw in the geological contacts on each side of the block. Also state the name of the geology feature in the diagram. 1 the top of the block is a horizontal plane a dipping bed that intersects it forms a strike line.

Block diagrams are a combination of geologic maps and cross sections illustrating both surface features and cross sections through the earth. Information given by the block diagram. A guide to block diagrams. Later still the anticline was truncated by an erosional.

Another illustration is a block diagram. B sedimentary beds 1 7 were deposited as horizontal layers. Structural geology is the study of the ways in which rocks or sediments are primarily arranged and secondarily deformed on the earth. You can create your own topography and show the outcrop pattern of geologic beds folds dykes or faults in seconds.

Next the gneissis cut and displaced by the faultlabeled a. Figure 1 a sedimentary beds 1 3 were deposited as horizontal layers.
