1. The study of strata on a small or very detailed scale.
1934Geogr. Rev. 24 150 The importance of ‘microstratigraphy’ (geochronology and micropaleontology) for correlation of Quaternary deposits is stressed by Helmut Gams. 1948New Phytologist 47 236 It seems desirable to push still further with the kind of micro-stratigraphy that is exemplified by the work of Granlund, Nilsson, and Ording. 1963Science 27 Dec. 1646/1 Notwithstanding these deficiencies..a clear presentation of the principles of micropaleontology and microstratigraphy is provided in the introductory chapters. 1992Cambr. Encycl. Human Evol. v. iv. 189/1 Microstratigraphy aims to reconstruct the centimetre-by-centimetre details of particular environments, often at important palaeontological or archaeological sites.
2. The detailed stratigraphical features of a site, geological deposit, etc.
1948New Phytologist 47 236 We may well get some fresh evidence from the micro-stratigraphy of bogs somewhere in continental Europe just at the limits for ombrogenous peat formation. 1976Current Anthropol. 19 392 In the absence of a preserved visible microstratigraphy in open-air sites, we are led to the tentative conclusion that occupation was sporadic by a small number of highly mobile groups. 2000Police Rev. 4 Feb. 19/2 Detailed examination of the micro-stratigraphy and distribution of the mud suggested the mud had been accumulated off-road over a short period of time and recently. |
