Stratigraphic charcoal analysis on petrographic thin sections : application to fire history in northwestern Minnesota
Results of stratigraphic charcoal analysis from thin sections of varved lake sediments have been compared with fire scars on red pine trees in northwestern Minnesota to determine if charcoal data accurately reflect fire regimes. Pollen and opaque
Stratigraphic and tectonic framework of the Ligurian Units in the Castellina M.ma Hills (southern Tuscany, Italy)
Ligurian ophiolitic complexes crop out extensively in southern Tuscany. In this paper the AA. present new data on the Castellina M.ma Hills ophiolite-bearing units, and review and discuss implications for the regional stratigraphic and structural
A palynological and stratigraphical study has been performed on glacial, interglacial and interstadial deposits outcropping in the Dranse river valley and which have been reached by two drill holes (Sionnex and Royal) near Evian. Ages
of these different deposits and their stratigraphical correlations from paleobotanical data and from 14C datations are discussed. The complete stratigraphical series is believed to include the Riss-Würm, the Mesowürm and the Neowürm.
The stratigraphic subdivision of the Lateglacial of NW Europe: a discussion in Studies in the Lateglacial of North-West Europe.
stratigraphic procedures, the error sources and resolution of radiocarbon dating, the basis of Lateglacial chronostratigraphic schemes, and the validity of defining boundaries on continuous curves of environmental change. A general climatostratigraphic scheme
Europe is a natural geographical region for a common Quaternary stratigraphic nomenclature, and there does seem to be considerable agreement on the Lateglacial climate of this part of the world.
The granulometric composition and sorting of loesses and interbedded soils are studied for stratigraphic subdivision and correlation of the loess-paleosol sequence in Moldova. Distinctive features of loess and paleosol horizons of different age
are identified and general characteristics of the mineral composition are described that together with other lithological characteristics, improve reliability of stratigraphic operations.
Stratigraphic revision of the Cenozoic deposits of the Lungro-Verbicaro Unit (Northern Calabria): new data for the reconstruction of tectonic evolution of the southern Apennines
New stratigraphic subdivision and typology of soils of the Late Pleistocene in loess series of the Danube Lowland in Czechoslovakia in Lithology and stratigraphy of loess and paleosols.
Ashlar-built maritime installations along the southern rim of the tel. The main goal of the exacavations was to try to find better stratigraphical and architectural interrelations between the series of quays and landing stages along the waterline
and the inshore structures which were not affected by sea-waves and are stratigraphically undisturbed. It seeems that the need of a higher pavement was caused by the rising sea level.
Here two commercially-acquired seismic reflection profiles are used to establish the structure and stratigraphic relationships between the frontal part of the orogenic belt, the foredeep and foreland regions in the offshore continuation
of the Apennine system in the northern Ionian sea. Given the proximity of this study area, the tectono-stratigraphic relationships imaged on these seismic lines are likely to provide good analogues for Neogene basins and depositional systems for much
of the Apennines onshore. Syntectonic basins are narrow, long-range stratigraphic continuity is likely to be the exception rather than the rule. This challenges some of the assumptions behind existing tectonic models for the Apennines and similar orogens. - (NF)
Field and laboratory analyses carried out on the sedimentary successions of Monte San Giovanni Campano, Fontana Liri and Rocca d'Arce (southern Latium) allow the AA. to recognize some unconformity-bounded stratigraphic units (UBSU) within
the Messinian portion of the local stratigraphical succession. The structural and stratigraphic features of the recognized UBSU allow the AA. To locate their related sedimentary basin within the frontal portion of the Apennine chain, behind the leading edge
Tectono-stratigraphic evolution of a basin generated by transpression : the case of the Early Pliocene Lascari Basin (northern Sicily)
Mountains (northern Sicily). This paper presents an original interpretation of the stratigraphic and structural evolution of the study sector of the Sicily Fold and Thrust Belt. Our data contribute also to both define the structural style and constrain
Stratigraphic evidence for the uplift of the Tibetan Plateau between 1.1 and 0.9 myr ago
Uplift of the Tibetan Plateau is manifest not only in widespread denudation, but also by an increased deposition rate of sediment, near or far from the exhumed regions. This paper uses the stratigraphic evidence to examine the timing of the Tibetan
Stratigraphic and microfossil evidence for late Holocene tsunamis at Swantown marsh, Whidbey Island, Washington
The AA. report stratigraphic and paleoecologic findings from a tidal marsh on the west coast of Whidbey Island, Washington, where 4 muddy sand layers were found in the peat underlying the marsh. These sand sheets record repeated inundation
