vulcanoclastic Explanation: Ciao, M. -------------------------------------------------- Note added at 2002-05-30 09:03:45 (GMT) -------------------------------------------------- \"Considering the asymmetric submerged setting of the Pontine volcanic edifices, which are bordered by basins landwards and are markedly steep-sided towards the slope, tectonic and volcano-tectonic failure and gravitative collapse are likely to have frequently occurred seaward, displacing volcanically-derived debris into the adjacent Tyrrhenian bathyal plain. Several vulcanoclastic dredged samples have been recovered from the Ponza slope (Zitellini et al., 1984) and major amounts of volcanic products from the Pontine Islands are believed to lie at greater depths, transported from both channelised fluxes and diffused mass- wasting.\" -------------------------------------------------- Note added at 2002-05-30 09:07:01 (GMT) -------------------------------------------------- OR: volcanoclastic (I found several US sites) Volcanoclastic Processes and Products http://geont1.lanl.gov/HEIKEN/one/other.htm for a comprehensive review of the literature to that point see Frey (1987)---had been concentrated on mudstones, volcanoclastic rocks, and associated lithologies common to continental mountain belts and arcs. In the mid 80\'s, results of the Deep Sea Drilling Project (DSDP) rather dramatically mitigated a shift in the study of low grade metamorphic rocks. http://earth.agu.org/revgeophys/schiff00/node1.html -------------------------------------------------- Note added at 2002-05-30 09:24:21 (GMT) -------------------------------------------------- You will probably get many replies as to what a hoodoo is: a highly eroded rock pinnacle, from severe gully erosion or badlands, usually in soft rock capped by a more resistant hard rock remnant. They occur as you mention in the soft shales of Zion National Park in Utah, and also (more notably) nearby in Bryce Canyon National Park, and in other areas of the Colorado Plateau. I have also noted hoodoos in soft tuff or other ** volcanoclastic rock **, such as in the San Juan Mountains of Colorado, and the Superstitian Mountains of Arizona. http://math.amu.edu.pl/~sgp/gw/hd/hoodoo.htm |

volcanic clasts Explanation: as opposed to pyro-clasts. BTW volcanoclastic (and pyroclastic)are fine. See ref. it might be useful. Cristina Reference: http://www.geol.ucsb.edu/~fisher/frags.htm |
