Quezon City, Manila, Philippines

San Francisco Del Monte Area

I have recently purchased around 20-25 kilos of tektites that were found on a small plot in the San Fransisco Del Monte area of Quezon City, Manila. This is a great collection and will be subject to future research.

These tektites are unremarkable. Smooth and water worn, commonly exhibiting no U-grooving, which is usually characteristic of the Philippinites. Seeing these tektites really helps me to understand Beyer's descriptions and appreciate how different these tektites are from other localities. These are perhaps similar to ones recovered at the Santa Mesa Site as oppose to Beyer's San Fransisco Del Monte site. There is a nice story attached too. These tektites were collected by these guy's grandfather, Colonel Arcadio G. Lopez from the plot he purchased in around 1965. The plot was 370-400 square metres and the tektites were found whilst planting palm trees and other plants (i.e. no deeper than a few feet). Tim even wears a polished tektite chain around his neck, which came from this site, and Carlos carries a tektite for luck. The Grandfather, deposited a few of these specimens in Singapore Museum in around 1994/5 - we will be following this up!

The tektite concentration here is at least 50 grams per square metre and almost certainly more! These tektites have definitely been transported and likely concentrated, but it shows just how many must have fallen!

ABOVE: Des Leong, Tim and Carlos (cousins)- whose grandfather collected the tektites from the plot whilst planting trees. All were found within a metre of the surface. Des is holding my new copy of Beyer's book - I am very pleased finding this copy in such good condition.

ABOVE:  Note the smooth nature of the tektites.

ABOVE: A close-up of the most typical tektites.

ABOVE:  Selected tektites from this loacality.

ABOVE:  The largest specimen, weighing in at 248.7g.

ABOVE:  89.1g and 95.0g 'breadcrust' specimens. Note that the cracks are thin compared to most of the Bikol region tektites. 

ABOVE:  118.2g and 70.2g 'breadcrust' specimens.

ABOVE:  A 4.3g teardrop and 37.7g 'biscuit-form' tektite. Note the generally smooth sculpture and the poorly developed U-grooves on the 'biscuit-form' specimen.

ABOVE:  A couple of dumbbells also with smooth surface sculpture.

ABOVE:  Some specimens, such as this 21.0g 'teardrop' and 33.5g biscuit-form, were heavily corroded, giving a vesicular-like appearance on both the posterior and anterior surfaces equally.

ABOVE:  Finally, most corroded of all, was this clinker-like, industrial slag-like glass. On first viewing I thought a lot of it might be industrial and non-tektitic. It was simply too vesicular, had more of a greenish-black colour and had a slightly waxy surface appearance.

ABOVE:  The two specimens on the left are definite tektites, whist the three on the right are this vesicular industrial slag-like material. The colour is identical! These specimens are actually true tektites - they are simply heavily corroded. This is certainly a learing point here - the 'bubbles' look like original features, but I'm pretty certain they are due to corrosion.

ABOVE: The plot where the tektites were collected from. This site is now largely built over, as you can see. The location is 78 West Avenue, corner of Examiner Street, West Triangle, Quezon City, Manila, Philippines - I'll google it when I get time!
