I still don't understand how that happened other than to think that somehow they didn' pay enough attention to the conference chair Andrew Miall - a noted clastic sedimentologist and maybe somebody the CSPG thought would be friendlier to their policy statement.
Belize shelf - carbonate sediments, clastic sediments, and ecology.
The surface geology of this ecoregion consists of clastic sedimentary rocks and recent alluvium.
On shore, 5 m sand dunes and alluvial sands and gravels overlie relatively recent sedimentary, Tertiary clastic and PreCambrian crystalline rocks.
The caves that have been created are some of the largest found anywhere in the world, and are superb examples of tropical river caves with flood incuts, extensive clastic sediment deposits and ellipticle tubes linking different cave levels.
This quaternary plain was formed by the post-orogenic clastic depositing of sediment, derived from adjacent tectonic uplifts deposited in the basin of the lower Magdalena River that formed a platform of peat intercalated with sand and clay beds.
Similarly, geomorphology varies from a low-gradient slope along the alluvial coastal plain, composed primarily of unconsolidated sediments to steeper gradients of acidic rocks of igneous origin and clastic sediments as one moves up into the mountains.
The transition back to clastic sediment deposition between 5550 14C yr B.P. and 3950 14C yr B.P marks the end of this warming period and the beginning of a neoglacial interval.
A small peak in clastic sedimentation was followed by a larger peak in glacigenic sedimentation, and presumably of ice extent, late in the Neoglacial interval Leonard and Reasoner, 1999.
The Cobalt Plain in the northeast section of the Ontario portion is composed of flat-lying clastic sediments with ridges and hills formed by gabbro sills or granitic rock inliers.
