High-resolution records of the late Paleocene Thermal Maximum and circum-Caribbean volcanism: comment and reply
Article Abstract:
The allegation by Gerald R Dickens that the association of the late Paleocene thermal maximum (LPTM) with abrupt changes in the global carbon cycle was baseless is untrue. The assertion was based on a study by Dickens et al. in 1995. In the study, Dickens inadvertently contradicted himself when he claimed that modern global changes were influenced by the abrupt change in global carbon cycle during the LPTM. Moreover, the analysis of methane hydrate dissociation is more useful in understanding the LPTM than the massive carbon dioxide input proposed by Dickens.

High-resolution records of the late Paleocene Thermal Maximum and circum-Caribbean volcanism: comment and reply
Article Abstract:
The statement by Timothy J Bralower et al. that abrupt changes in the global carbon cycle occurred during the late Paleocene thermal maximum (LPTM) failed to eliminate alternative interpretations of the massive carbon dioxide (C02) input during that period. Their interpretation of the carbon isotope records around the Caribbean Area during the period was inconclusive. The massive input of CO2 to the ocean floor over a long period combined with carbonate dissolution can be an alternative interpretation of the LPTM.

Mariana blueschist mud volcanism: implications for conditions within the subduction zone
Article Abstract:
Non-accretionary Mariana convergent plate margin mud volcanoes are found to be spewing slab-derived fluids and serpentine rocks. The area, where the mud volcanoes are located, is between the Mariana trench and volcanic core. It is pervasively faulted and contains seamounts composed of unconsolidated flows of serpentine mud with clasts of mantle peridotite. Data on decollement materials, mass fluxes and geochemical interchanges have been based solely on drill cores located in these accretionary convergent margins.
