What is Honest bookkeeping for source-to-sink sediment mass-balance analysis with examples from the Angoche margin of Mozambique and the Corsica trough of France about?

If sediments in a basin share a similar genetic history (derived from a common place, from a common suite of raw materials, under a common set of environmental conditions, and subsequently experienced a common burial and thermal history), then physical characteristics of those sediments should be internally consistent and inferences about one physical property in one part of the basin can be drawn reliably from other physical properties in other parts of the basin. Balanced mass between a prospective source and an observed sink can indicate shared genetic history. If the sediments in the sink don't balance with the source, then additional history must be accounted: perhaps other sources, or perhaps leaks. Balance can only be evaluated with deliberate analysis that precisely defines and accurately measures the relevant physical boundaries and conditions of the sink and the potential sources. The analysis must start with the sink and work backward to potential sources. An example from sediments of the last 190 Ma on the Angoche margin of Mozambique demonstrates that the immediately adjacent hinterland of a basin may not supply all the sediment, so that exotic sources must be consider
