Washington Geological Survey, 2020, Preliminary Depth to Precambrian Basement of the Okanogan Highlands, Washington State

Summary

This model represents perhaps the first attempt at a Precambrian basement model for the Okanogan Highlands. It incorporates a wide variety of data sources from varying scales to as input to the basement model. However, significant improvements to the model are possible with additional data and refined methods. For example, study- wide 1:24,000-scale mapping would greatly improve the resolution of the mapped basement extent. Refined age dating for the Okanogan Core Complex would also address the age of the terrain and whether it is appropriate to include with Precambrian aged rocks. Refined methods of modeling in areas of shallow sediment thickness, would reduce the uncertainty in many areas. Incorporation of geophysical data collections, [...]

Purpose

As part of the USGS 2019 Earth MRI Grant the Washington Geological Survey (WGS) was tasked with creating a depth to Precambrian basement dataset for relevant areas in the state. For this, we limited the extent of the study area to the northeast corner of the state known as the Okanogan Highlands. This is for two reasons, firstly it is where the largest concentration of Precambrian basement can be found in the state and secondly it is in an area that has a long mining history and may be favorable to potential exploration in the future.
