That bedding plane is 1. a primary depositional lamination in sedimentary rocks that may be preserved, though possibly with different properties, in metamorphic rocks. these laminations may be clearly visible where lithologies change or where depositional cycles were completed/initiated, or they may be effectively invisible to the naked eye, marking subtle changes in depositional conditions. most bedding planes were originally horizontal or very slightly inclined, but more steeply inclined bedding planes developed in rocks deposited in deltaic or sand dune environments or in marine reefs. when rocks are folded the bedding planes provide an indication of the degree of deformation. bedding planes play a crucial role in the inception and ongoing development of most caves and many surface karst features [3]. 2. a plane that separates two strata of differing characteristics [10]. see also parting.?

Development of the carbonate island karstmodel
Abstract:
The development of a comprehensive conceptual model for carbonate island karst began in the Bahamas in the 1970s. The use, initially, of cave and karst models created for the interior of continents, on rocks hundreds of millions of years old, was not successful. Models developed in the 1980s for the Bahamas, that recognized the youthfulness of the carbonate rock, the importance of fresh-water mixing with sea water, and the complications introduced by glacioeustatic sea-level change produced the first viable model, the flank margin cave model. This model explains the largest caves in carbonate islands as being the result of mixing zone dissolution in the distal margin of the fresh-water lens, under the flank of the enclosing land mass. The flank margin model, taken from the Bahamas to Isla de Mona, Puerto Rico, in the early 1990s, provided the first viable explanation for the very large caves there. Field work in the geologicallycomplex Mariana Islands in the late 1990s resulted in the development of the Carbonate Island Karst Model, or CIKM, which integrated the various components controlling cave and karst development on carbonate islands. These components are: 1) Mixing of fresh and salt water to create dissolutional aggressivity; 2) Movement of the fresh-water lens, and hence the mixing environments, by 100+ m as a result of Quaternary glacioeustasy; 3) The overprinting of glacioeustatic changes by local tectonic movements, where present; 4) The unique behavior of eogenetic (diagenetically immature) carbonate rocks; and 5) The classification of carbonate islands into simple, carbonate cover, composite, and complex categories. Current research involves the use of flank margin caves as predictors of past and present fresh-water lens configuration, the analysis of flank margin cave morphology as a measure of the processes that create them, and the CIKM as an indicator of paleokarst distribution.
