Palaeoenvironmental Reconstruction of the Miocene Tepoztlán Formation (Central Mexico): Preliminary Results of Palynological Investigations.
In: AMCS Bulletin, 19, pp. 158-161. [Article]
Abstract
In Miocene times, a major volcano- tectonic change took place due to a re - or gan ization of the tectonic plates in the western Pacific region. Since the Mid-Miocene, the Transmexican Vol - canic Belt (TMVB, Fig. 1) began to form (Delgado-Granados et al. 2000). However, there is still a controversial scientific debate on its development. The aim of our study is to establish a stratigraphic framework and a palae - oenvironmental interpretation of the Mid-Miocene Tepoztlán Formation. To date, palaeobotany in volcanic settings has dealt with intercalated sedi - ments namely paleosoils, fluvial volcani - clastic sandstones, peat or lignites (e.g., Lund 1988, Hilton et al. 2004). Even authors working on tuffaceous mate - rial focussed on either the macroflora (e.g., Pole 1994) or charcoals (Scott and Glasspool, in press). Publications on palynology in pyroclastic rocks and their reworked deposits (lahars and flu - vial deposits) are rare (Satchel 1982, Taggert & Cross 1990, Jolley 1997, Bell & Jolley 1997). In this study we investigated a volcaniclastic section of the Mid-Miocene Tepoztlán Formation with respect to palaeoenvironment using palynology. This method has not been applied to this formation previously.
