Tectonic Pattern

The interests of forecasting of the area’s development simulate to take more attention to the study of its newest tectonics. The most informative tectonic pattern for the studies of coastal zones is neotectonic one, based on the structural principle, which shows the newly formed and inherited dislocations, reflected in the modern landscape and exodynamics of the earth's surface. The question of the manifestations of newest tectonics by way on the example of the Vistula Spit (Baltic Sea) is discussed.

Tectonic Pattern

AbstractIn the Clashnessie district the original or Scourian complex is represented chiefly by hornblendic gneisses and shows simultaneous close folding on 55°–235° (A 1) and 155° (A 2) axes. The general disposition of the formations is largely related to open folding on the A 1 axis.The effects of later movements, post-dating the basic dykes, are comparatively slight, but are shown by the sporadic development of a schistosity and a lineation, which plunges to the south-east, together with occasional sharp folds at about 207° (A 3) and 114° (A 4).

Tectonic Pattern

abstract A statistical method devised earlier by the writer for the tectonic interpretation of fault plane solutions of earthquakes, is applied to fault plane solutions of Arctic earthquakes which were recently published in Russia. It is shown that the earthquakes on the Greenland side of the Arctic seismic belt represent the same tectonic pattern as seen on the Mid-Atlantic Ridge, whereas the earthquakes on the Siberian side are tectonically connected with the Verkhoyan range.

Tectonic Pattern

Pan-African deformation in the Zambezi Belt appears to be dominated by the development of domes and periclines cored by gneiss, whose growth has swept aside the overlying meta-sediments and constricted them in synclinoria which tend to be disposed tangentially about the main domal structures. Because of this arrangement, horizontal displacements tend to cancel out. By using strain data derived from pebbles in conglomerates which form part of the deformed sequence and by modelling the body rotations involved in this kind of tectonic pattern, shortening across part of the Belt in Zambia is estimated to be not more than 8 km or 14 %. The method is extended by using strain data from elsewhere in the Belt and by making further assumptions and extrapolations, to a section 230 km long extending to the northern margin of the Rhodesian Craton. Estimated shortening across this part of the Belt is unlikely to exceed 70 km or 25 %.

Tectonic Pattern

A significant correlation exists between direction patterns in magnetic and tectonic trends on the northern two thirds of Texada Island, British Columbia, Canada. The patterns were analyzed in further detail by dividing the area into regions based on amplitudes of magnetic anomalies and on patterns in the magnetic trends. A technique involving smoothing and crosscorrelation was applied in the examination of the relationships between the patterns. The regions established on a magnetic basis also are distinct on the basis of tectonic pattern. However, correlation between the magnetic and tectonic patterns varies from region to region within the area. The directions N 50° W, N-S, and E-W, common throughout the coastal area of British Columbia, are the most widespread in the patterns studied on Texada Island. A distinctive zone, identified as a fault zone cutting across the island with a trend of N 20°W stands out in the patterns.
