Comments on the geologic information

  • Geologic Description = Lost River is the main south-flowing drainage in the York Mountains. Bedrock in this drainage and its tributaries are various Ordovician limestone facies locally intruded by felsic and mafic dikes and granite stocks (Sainsbury, 1969). Although the lower part of this river is in an area where marine terraces are prominantly developed, this locality appears to be in alluvial gravels of the active drainage where it crosses the lowland adjacent to the present shoreline. One USBM churn-drill hole here encountered 5.5 feet of gravel over limestone bedrock that contained 0.09 pounds of tin per cubic yard (Mulligan, 1959, p. 13); information on the mineralogy of this material was not given.
