7 m depth where diamicton
was observed at stream level in WM.
The percussion coring of the basin further showed that coarse diamicton
is overlain by coarse, granite-rich, moderately sorted sediment which, in turn, is overlain by alternating layers of gyttja and wetland sediment.
Till is a silt and clay-rich diamicton
with a mean matrix texture of approximately 21% sand, 45% silt, and 34% clay, a Munsell color of 10YR 4/6 to 7.
Based on earlier stratigraphical observations, stratified sands occur at the bottom of a 3 m deep section, under a 2 m thick diamicton
El termino diamicton
se refiere principalmente a los flujos volcanicos no clasificados que rellenaron valles, introducido por Koch & McLean (1975), denominado como "Flujo los Chocoyos", que se caracteriza por presentar una zona de color rosado ("pink zone").
This buried ice is interpreted as glacier ice and is overlain unconformably by 1 -2 m of icy diamicton
If the recovered material is diamicton
or till, the distance the wood was carried is unknown.
Additionally, small plastic canisters were driven into a freshly exposed profile at 10 cm intervals from the surface of the profile to the underlying glacial diamicton
14] BP (Porter and Swanson, 1998) and it deposited an ice-contact diamicton
of variable thickness throughout most of the basin.
Overlying the mudflow, Unit 4, a silty diamicton
with a relatively high carbonate and organic content, appears to have formed by a mix of natural colluvial and human transport processes, and is associated with human cultural material.
Raukas (1978) first mentioned a theoretically possible distribution of waterlain diamicton
on Estonian territory.
In the Fault and Evaporite districts, the topography over the steep slopes is bedrock-controlled, with minimal glacial diamicton
and covered by primarily an Acadian hardwood forest.
