Interplanetary space is populated with large
numbers of small bodies in orbits that can intersect those of
planets and moons. Therefore, individual impacts appear on the
surfaces of planetary bodies which are called impact craters.
While impacting meteorites are useful in determine the early
solar system processes, resultant impact craters are useful to
determine the ages of the surfaces and related erosional effects
on the body. At ÇOMU (Çanakkale Onsekiz Mart University) we
aime to create a Meteorite/Impact Craters Data Base of Turkey in
a computer environment. The data base will be reachable through
internet for wider use. Preparations and actions for this
exercise will be presented.
For the initial phase, we have collected related information
through the scientific and literary books, papers and thesis on
the topic. We can classify our present efforts on meteorite/impact
crater event identification along following lines. 1) Meteorites
which have fallen down to our country recently (i.e., Antalya
meteorite in 2001, Afyon meteorite in 2002 and others); 2)
Meteorite and their impact craters, which mentioned in
historical records (Gallipoli meteorite, 467 BC; Birgi meteorite,
1335 AD etc.); 3) Candidate impact craters in Turkey which were
studied earlier (Dağcı, 1997; Özel et al., 1998); 4) Other
events that can be recognized through sattellite images and maps;
5) New events during our preparations.
These candidates and
established structures will be investigated and relevant data
will be used for the aimed data base. We aim to complete the
exercise by 2006.

which are countered as the primitive samples of matter that
constitute the solar system have important knowledge about their
parent bodies and the interplanetary space. Meteorite carry some
traces much occur during their staying in interplanetary space
and passing through a planetary atmosphere before reaching at
the surface of a planet. Information about early solar system
processes can be determined from the classification of
meteorites. A classification of meteorites based on their
mineral composition and chemical properties are usually carried
In this study, we
have carried out some investigation and chemical analysis on
meteorite candidates found in Turkey. The results of chemical
analysis (some major and minor element abundances) of samples
will be represented and will be compared with the literature.
Since there is no national information system in this area, we
also aim to create such a database for Turkey.

SACRED STONES FROM SKY
Sibel ÖZMAYA, Özlem KOCAHAN, Mehmet Emin ÖZEL
Meteorites which are stony and iron remnants from early solar
system, falling on the planetary surfaces including Earth, have
also been used as sacred stones from gods, throuhout the human
history. Most famous example still having a sacred function is
in the Kaaba, at Mecca. There are other examples of historical
records where such stones are mentioned and sometimes,
sacrificed. Artemis Temple of Ephesus did contain such a stone
which is still not discovered and/or missing. The well-recorded
467 BC meteorite that fell to Gelibolu peninsula and known to
be examined by Anaxagoras of Lampsakos (present day Lapseki) may
have beneen related to the sacred stone of Artemis Temple.
Samples of such stones, when dated by the methods of
achaeophysics and archaeometry will increase our understanding
of our past and the present. As part of the Archaeometry Program
at Çanakkale University (ÇOMÜ) investigation of such historical
records and related findings is also aimed and other possible
historical cases and examples will be presented.

We present new CCD photometry of some Near Earth Asteroids, together with their earlier observational data from the literature. The light variations were analysed and interpreted in terms of the physical parameters of the asteroids.
