Field studies in this province were conducted intermittently from 1944 to 1960 as part of the U.S. Geological Survey program of petroleum investigations in southern Alaska. The geology shown on two previously published maps of the Malaspina district was combined, revised, and plotted on an updated base, with a geologically complex area in the Samovar Hills also shown on a larger scale insert. Previously published descriptions of bedrock geology and surficial deposits apply to this compilation except where modified by new stratigraphic and structural interpretations. Rocks formerly assigned to a crystalline complex in part of the Samovar Hills were reinterpreted as a volcanic unit of probable Mesozoic age, consistent with correlations in adjoining districts. The crystalline complex north of the Chugach St. Elias fault was considered to include more metamorphosed equivalents of this volcanic unit and possibly older Paleozoic rocks. Newly collected fossils supported a Late Cretaceous age for the Yakutat Group, and rocks previously mapped as an early Tertiary siltstone sequence were reassigned to an undifferentiated sedimentary unit of Paleocene and Eocene age. Surficial deposits previously divided into fourteen units were simplified into four broader map units on the present compilation. The dataset provides geologic, structural, stratigraphic, and geochronologic information organized according to the GeMS and AK GeMS mapping schemas. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: https://dggs.alaska.gov/pubs/id/10668. Purpose: The purpose of this report was to document the geologic mapping and stratigraphic interpretations of the Malaspina district within the Gulf of Alaska Tertiary province, based on field studies carried out between 1944 and 1960. The report preserved the geologic framework developed during early U.S. Geological Survey petroleum investigations and provided a consolidated record of mapping, unit correlations, and revisions made at that time. By integrating earlier maps, updating unit assignments using information then available, and simplifying surficial categories, the report served as a historical reference for regional geologic research, stratigraphic studies, and the development of geologic mapping practices in southern Alaska.

Two previously published maps of the Malaspina district were combined, revised, and transferred to an updated base, with the complex Samovar Hills area shown on a larger scale insert. Published descriptions of bedrock and surficial units were incorporated except where modified by new stratigraphic and structural interpretations. Fossil data were used to refine ages of key units, several rock units were reassigned based on revised correlations, and surficial deposits were simplified from fourteen units to four broader map categories. Process_Date: 1960 Process_Step: Process_Description: Data packaging - DGGS organized and attributed the geologic and geographic features according to the AK GeMS schema, then programmatically transformed the data into four distribution formats: (1) an AK GeMS data package containing the full database and supporting files, (2) a GeMS data package converted to the USGS base standard, (3) a SQLite database file, and (4) a simplified shapefile package with shapefile representations of the data.
