Microplankton and sedimentological studies in the Nûgssuaq and Disko region, central West Greenland

Abstract

In 1975 the Danish Natural Science Foundation (SNF) and the Geological Survey of Greenland (GGU) initiated an investigation of the microplankton (dinoflagelIate cyst) of the Cretaceous and Tertiary sediments in central West Greenland. The purpose of this investigation is the establishment of a dinoflagelIate stratigraphy based on samples from measured sections to assist in a basin analysis. SNF provided the funds for the establishment of a laboratory for palynological preparation and investigation. They also funded a Leitz Orthoplan microscope with a Leica camera for the study of the microplankton, and two of the six Honda ATC 90 motor tricycles that facilitated the field work. The main field activity in 1975 has been outlined by Croxton (this report). As mentioned by Schiener & Henderson (1975), seven weeks field work were carried out in 1974 by the writer and T. Jürgensen. In 1974 ten sections (M1 - M10) totalling 2670 m of sediment were measured and 201 samples were collected. T. Jürgensen also measured a series ofsections (T2 -T14). In 1975 nineteen sections(M11-M29) were measuredand 837 samples were collected (see fig. II for localities).
