Studies in East Asia Tectonics and Resources (SEATAR)

Data Announcement 81-MGG-04

     Geological and geophysical data from the SEATAR project . The SEATAR project was funded through the National Science Foundation's International Decade of Ocean Exploration (IDOE) program, and involves investigators from several academic institutions.

     SEATAR is a comprehensive study of the relationship between the Southeast Asian tectonic framework and the genesis of metalliferous ores and hydrocarbons. It is the result of a 1973 workshop held in Bangkok and is sponsored by the Committee for Coordination of Joint Prospecting for Mineral Resources in Asian Offshore Areas/Intergovernmental Oceanographic Commission (CCOP/IOC).


1. SEATAR atlas data*:

     a. 8 magnetic tapes containing core locations and descriptions, camera station data, paleomagnetic data, heat flow measurement, earthquake focal mechanism solutions, sonobuoy data, and underway geophysical data in the merge-merge format for 178 cruises.

     b. 1 reel of 35-mm microfilm and 1 microfiche containing Lamont-Doherty Geological Observatory (LDGO) sonobuoy data, data locations, and water depths.

     c. 9 microfiche containing LDGO seismic profiles.

2. Additional SEATAR data

     1 magnetic tape containing sediment descriptions, texture, and geochemical analyses for 8,168 samples as compiled by Scripps Institution of Oceanography. This portion of the data set is available for free download online.

3. Other data:

Geophysical data for over 150 cruises in Southeast Asia not included in item 1 above are also available. These data were collected by several institutions and include more than 400,000 n.mi. of magnetics, 250,000 n.mi. of gravity, and over 125,000 n.mi. of seismic reflection. Some data are digital, others are available on 35-mm microfilm.

Over 4,000 additional sediment analyses are also available. New data of all types are constantly being received. Inquiries about price and availability are invited.

*Lamont-Doherty Geological Observatory of Columbia University has integrated data from various sources to produce a "Geophysical Atlas of East and Southeast Asia" (D.E. Hayes, 1978). Data used in compilation of the atlas as described in item 1 above. The geophysical atlas consists of six folded maps and eight pages of text, and is available as MC-25 of the Map & Chart series from the Geological Society of America, 3300 Penrose Place, Boulder, CO 80301.
