The rock lithology varies from Permian to Upper Cretaceous-fractured Hawasina Complex and Semail Ophiolites in Masfut, Quaternary eolian sand
in Manama and Quaternary sand dunes in Ajman city.
The second exposure was located under eolian sand
cover approximately 25 m below the level of the initial Descubridora I exposure and 30 m along trend to the southwest.
There are two narrow west-east trending fields of eolian sand
dunes overlying the formation, and much of the southern region of the AVA is generally overlaid with upper Quaternary sand sheet deposits (Holliday 2001).
Sand barrens are located on eolian sand
deposits and are mostly positioned on the leeward side of the river.

Contemporary and historical rates of eolian sand
transport in the Indiana dunes area of southern Lake Michigan.
Finally, a large open cut has been developed on the Descubridora I and II exposures to extract high grade, near surface material exposed in bedrock immediately underlying eolian sand
However, it is not known whether this eolian sand
is the same age as Unit VI.
Based largely on grain size distribution, we interpret the material that buries the basal soil as eolian sand
In addition, given the recent increase in the price of iron, sampling will include samples of the magnetite-bearing eolian sand
which covers the majority of the Angela tenures.
in the uppermost mud is variable, and occasional bands of sand may relate to when the dunes lost their wooded cover -400 yr.
Recent exploratory work is interpreted to indicate excellent potential for identification, and subsequent development, of multiple, high grade copper mineralized veins over a large area, potentially extending from the Roble tenures, through the eolian sand
covered Angela tenures to the south, southwest and west.
