Abstract:

Saint Lawrence Island is located in the northern Bering Sea, 190 km southwest of the tip of the Seward Peninsula, Alaska and 75 km southeast of the Chukotsk Peninsula, Russia. It lies on a broad, shallow-water continental shelf that extends from western Alaska to northeastern Russia. The island is situated on a northwest-trending structural uplift exposing rocks as old as Paleozoic above sea level. The submerged shelf between the Seward Peninsula and Saint Lawrence Island is covered mainly with Cenozoic deposits (Dundo and Egiazarov, 1982). Northeast of the island, the shelf is underlain by a large structural depression, the Norton Basin, which contains as much as 6.5 km of Cenozoic strata (Grim and McManus, 1970; Fisher and others, 1982). Sparse test well data indicate that the Cenozoic strata are underlain by Paleozoic and Proterozoic rocks, similar to those exposed on the Seward Peninsula (Turner and others, 1983).

Saint Lawrence Island is 160 km long in an east-west direction and from 15 km to 55 km wide in a north-south direction. The eastern end of the island consists largely of a wave-cut platform, which has been elevated as much as 30 m above sea level. Isolated upland areas composed largely of granitic plutons rise as much as 550 m above the wave-cut platform. The central part of the island is dominated by the Kookooligit Mountains, a large Quaternary shield volcano that extends over an area of 850 sq km and rises to an elevation of 630 m. The western end of the island is composed of the Poovoot Range, a group of barren, rubble-covered hills as much as 450 m high that extend from Boxer Bay on the southwest coast to Taphook Mountain on the north coast. The Poovoot Range is flanked on the southeast by the Putgut Plateau, a nearly flat, lake-dotted plain that stands 30-60 m above sea level. The western end of the island is marked by uplands underlain by the Sevuokuk pluton (unit Kg), a long narrow granite body that extends from Gambell on the north to near Boxer Bay on the south. Headlands having rugged cliffs or narrow, boulder-strewn beaches characterize the southwestern coastline.

Purpose:

This data set represents part of a systematic effort to release geologic map data for the United States in a uniform manner. Geologic data in this series has been compiled from a wide variety of sources, published and unpublished, ranging from state and regional geologic maps to large-scale field mapping.

Data_Set_Credit:

This data set was prepared by Theresa Taylor (USGS), and Frederic Wilson (USGS).

Native_Data_Set_Environment:

Data set was created in a geodatabase and converted to a coverage using ESRI ARC\INFO version 9.3 on a Windows XP platform

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The geologic map of Saint Lawrence Island was prepared from published and unpublished field investigations carried out between 1966 and 1971. Vector features were mostly heads up digitized from a scanned paper map of hand drafted geology over a 1:250k topographic base. Vector and polygon attributes were assigned based on the original source. The digital data has been checked, and the geologic map has been technically reviewed and edited.

Logical_Consistency_Report:

Each geology coverage is a network coverage containing attributed arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults, stratigraphic contacts, and other linear features are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangling arcs may be present (faults, dike, etc.)

Completeness_Report:

The complete dataset consists of one geology network coverage (polygons and arcs), and one age coverage (points), marking the location of dated rock samples. There is also an associated relational database of geologic units. The coverage has the extent of all St. Lawrenece Island's 1:250,000 scale quadrangle. On the web page, the map will be provided as a database and a PDF; the pamphlet will be provided as a PDF.

Horizontal_Positional_Accuracy_Report:

This data is presented for use at a nominal scale of 1:250,000, although some sources were from 1:2,500,000, 1:500,000 scale mapping.

Lineage:

Process_Step:

Process_Description:

Line work for the geology compilation was head's up digitized from one scanned paper map source at 1:250,000 scale using ARC\INFO version 9.3. The arcs and polygons were attributed. The spatial databases are provided in UTM projection and geographic coordinates in coverage format.

Entity_Type_Label: polygons

Entity_Type_Definition:

Characteristics of the polygon features in the geology coverages are coded in the polygon attribute table. The table <cov>.pat includes the following items: CLASS, QCLASS, SOURCE, NSACLASS, NSAMOD, NSASUB, LABEL, MIN_AGE and MAX_AGE. CLASS is used as a key to identify and label units for the Saint Lawrence geologic map. NSACLASS is used for creating the generalized geologic map of Alaska.

Attribute:

Attribute_Label: LABEL

Attribute_Definition:

LABEL is a character field (6 8 C) which holds the label of the geologic unit.

NOTE: Because of the limitations of common GIS fonts, the letters "Mz", "Pz", "C", and "Z" are substituted for the standard symbols for "Mesozoic", "Paleozoic", "Cambrian", and "Proterozic".

The format for SOURCE is XX###, where XX is a two letter code for the 1:250,000 scale quadrangle and ### is a three digit number (with leading zeros). All source codes with '001' are unspecified sources for water and ice features, often paper topographic maps, and DRG or DLG files.

Attribute:

Attribute_Label: NSASUB

Attribute_Definition:

NSASUB is a positive integer value (4 5 B) item in the polygon attribute table. One value of 2410 is used in this dataset. NSASUB is a numeric code to identify underlying concealed geologic units for the statewide database. This field is used in specific cases where the author wants to represent both a bedrock unit that is not exposed in outcrop and the overlying quaternary unit. In the .pat, the NSASUB value defines the attribute of the concealed bedrock unit, while the NSACLASS and QCLASS define the attribute of the overlying unit. The CLASS value is used for classifying the solid color fill symbol. Polygons for these units are typically a lighter shade of color than the polygons for the same unit in outcrop. Concealed bedrock units are intentionally not labeled on the geologic map, instead, their geologic relationship and symbology are described in the unit description.
