The act of adding portions of soil to the soil already in possession of the owner by gradual deposition through the operation of natural causes.

The growth of the value of a particular item given to a person as a specific bequest under the provisions of a will between the time the will was written and the time of death of the testator—the person who wrote the will.

Accretion of land is of two types: (1) by alluvion, the washing up of sand or soil so as to form firm ground; and (2) by dereliction, as when the sea shrinks below the usual watermark. The terms alluvion and accretion are often used interchangeably, but alluvion refers to the deposit itself while accretion denotes the act. Land uncovered by a gradual subsidence of water is not an accretion; it is a reliction.

1 the natural increase in the area of land by accumulation of soil and the like. In Scotland the Roman term ALLUVIO is used for the same concept.

At this latitude, the Palaeozoic accretionary processes that occurred in the ancient southwestern margin of Gondwana start with the Cuyania collision to Gondwana (old Pampia terrane), causing to Famatinian orogeny in Ordovician times (Fig.
Others include that they may be accretionary lapilli formed in volcanic ash eruptions, impact spherules formed in impact events, or devitrification spherules resulting from formation of crystals from formerly melted material.
The relationship between the context of rumour and gossip, and what we might call narrative, is likewise ambiguous primarily because, being a accretionary process, rumour and gossip are part of the stuff of narrative formation itself; therefore, both narrative, proto-narrative and fact-statements co-mingle in a confusing sea of face-to-face verbal transmission (on narrative and ambiguousgenres see: Oring 1986: 121-122; Victor 1993: 72-73; De Vos 1996: 6).
Cuticle fragments of olenellid trilobites, for example, reveal minute pores and the details of terrace ridges (Butterfield and Nicholas 1996, figs 3.1-2), while shell layers from organo-phosphatic brachiopods exhibit a concentric accretionary pattern and sometimes a porous or granular texture (Fig.
They suggest that "existing survey information is inadequate to exclude the possibility of earlier Holocene human occupation" and predict that earlier sites may be found on low energy beach deposits and behind accretionary coastal barriers (e.g.
Eighteen contributed chapters honoring Windley's influence are arranged in sections on oceanic and island arc systems and continental growth, the tectonics of accretionary orogens and continental growth, growth and stabilization of continental crust (collisions and intraplate processes), Precambrian tectonics and the birth of continents, and active tectonics and geomorphology of continental collision and growth zones.
However, traces of accretionary lobes extending landwards to the south-east are evident along the southern shores of Al Aryam and suggest that the island is a composite of two former islands that probably nucleated on the vestiges of two(?) former seif dunes, eventually being linked by marine deposition in the form of beach bar sands.
