چکیده

The results of a comparison between two different submarine mass wasting events, using differing methods of investigation are presented in this study. Remotely sensed geophysical data types, such as 3D seismic, can be used to image and analyze large-scale examples. The strengths of such techniques lie in the ability to image large areas (i.e. 10’s of sq km), allowing consideration of the broad-scale architecture of the units. In contrast, field-outcrop studies allow more detailed analysis of geological features, down to a mm scale. Two slumps have been compared; one exposed in outcrop, the other imaged using 3D seismic data. The outcrop example comes from the Miocene of the Waitemata Basin, northern New Zealand, and the seismic example comes from the Pliocene of the Møre Basin, off-shore Norway, and occurs on a scale some 100 times greater that the field outcrop example. Despite this, the two examples exhibit similarities in their gross architecture, with each showing a bi-partite anatomy, well developed slump folds and geometrically similar basal shear surfaces. The results of the comparison emphasize the complexity of large-scale events, and illustrate the potential value of combining field outcrop data with geophysical data types.

Evaluation of Updating Methods in Building Blocks Dataset

With the increasing use of spatial data in daily life, the production of this data from diverse information sources with different precision and scales has grown widely. Generating new data requires a great deal of time and money. Therefore, one solution is to reduce costs is to update the old data at different scales using new data (produced on a similar scale). One approach to updating data i...

In this research, the microbiostratigraphy and depositional environmental implications related to the Surgah Formation at the northern flank of the Kuh-e Sepid anticline in the Lorestan Basin are discussed. A study of small planktonic foraminifera from the 101-m-thick Surgah Formation led to the identification of three Turonian–Santonian biozones: (1) Helvetoglobotruncana helvitica, (2) Margino...
