The age of Albanian Ophiolites has been determined by the age of siliceous sections, lying
above them. The aim of this study is to digitalize the data provided by radiolarian
assemblages yielded in this siliceous sections. Radiolaria are protozoic organisms with
siliceous shell, abundant in the sedimentary rocks lying above the ophiolites all over the
Tethys realm. The data for the Radiolarian Assemblages in Albania are taken from the Chert
sections which belong to the siliceous sedimentary cover of the ophiolite of the Mirdita Zone
and to the carbonate successions deposited on the continental margin of the ophiolites. These
data are abundant and the way that this information is available in the existing format, is not
convenient to be easily used. In order to resolve this problem we have developed a relational
database by applying MS Access techniques which will facilitate the use of this data from
different users. With this program we can provide the whole information when the section or
the sample is known, by using different queries. The whole information has been presented in
tabular form, with the tables interacting in a very harmonious and functional relationship with
each other. The tables contain information about chert sections in which the radiolarian
assemblages are taken: their location, position of samples in these sections, age, lithology,
photos etc. The tables also contain a lot of information about the radiolarian assemblages in
every sample: list of radiolarian species, age, author, species descriptions, photo etc. We can
also edit all this information or enter new data according to them. This database will be used
by geologists to better understand the problems regarding the age of the beginning of siliceous
sedimentation in different parts of Albanian Ophiolites, from north to south, from west to
east.
Key words: Radiolarian assemblages, Jurassic, chert, MS-ACCESS, database, section,
