WORKSHOP ON "CARIBBEAN GEOHAZARDS AND GEO-RISK RESEARCH AND PREVENTION"

As part of the forthcoming Earth Science Convention to be held in Havana, April 2017, a workshop is planned, dedicated to the continuous research about geohazards and associated risks in the Caribbean realm, which is a very important matter, as earthquakes, tsunamis, slope failure, erosion and other potentially dangerous events are present in the region and had cause major disasters in the past.

During this workshop will be examined the results of research and specially, positive and negative experiences regarding natural disaster prevention in the Caribbean region. It is also an aim of the workshop to coordinate disaster prevention efforts in the area.


WORKSHOP: VOLCANOGENIC MASSIVE SULPHIDE (VMS) DEPOSITS MODELS: CUBAN AND CARIBBEAN EXAMPLES.

Geologic setting and age of volcanogenic massive sulphide (VMS) mineralization in Cuba and the Caribbean. VMS deposit models, structure, alteration, mineralogy, geometry and exploration methodologies. Comparisons between modern and ancient sea floor mineralizing systems. Hydrothermal fluids, their properties and chemistry.


THE 3RD IGCP-649 WORKSHOP AND FIELD EXCURSION  

CUBAN OPHIOLITES, CHROMITITES AND PERI-CARIBBEAN MANTLE DYNAMICS

Co-conveners: A. Isabel Llanes Castro (Cuba), J.-S. Yang (China) & Y. Dilek (USA) 

The IGCP 649 project (2015-2020), entitled “Diamonds and Recycled Mantle”, is an approved and supported project by the UNESCO and IUGS. Recent studies of ophiolites show the presence of diamonds in both chromitites and peridotites in their mantle components. These “ophiolite-hosted diamonds” represent a new occurrence of ultrahigh-pressure (UHP) minerals, whose estimated pressure-temperature conditions indicate crystallization at mantle depths of 150-300 km or more. The IGCP project emphasizes the global importance of this work, and will hold the third IGCP-649 workshop and field excursion on ophiolites and chromitites in Cuba in April 2017, following by the first international workshop in 2015 in the North Qilian ophiolite of China, and the second workshop on the Troodos ophiolite of Cyprus in 2016. The workshop will bring together students, young professional and established researchers from the Americas (North, South and Central Americas and the Caribbean Region) to examine the distribution, geochronology and geochemistry of ophiolites and associated natural resources, and to discuss the mid-ocean ridge, plume and strike-slip tectonics related mantle dynamics and composition in and around the peri-Caribbean region. 

The 3rd IGCP-649 workshop and field excursion is part of the VII International Earth Science Convention to be held in Havana, Cuba, in April 2017, and will be co-organized with the Cuban Geological Society. Contributions are welcome on any aspects of the mantle dynamics, compositions and heterogeneities based on interdisciplinary studies of mantle xenoliths, ophiolites, and Deep Ocean Drilling core samples; UHP metamorphic rocks; and occurrences of different types of diamonds and their geodynamic settings of formation.
