Also, broken tektites were found at the same location by later researchers so transport and breakage of some and not others is likely. An important aspect of tektite history has to be the study which has been done by scientists. They have been studied now for well over a hundred years. They have been speculated about and argued over and this has caused them to be prized by both scientist and collectors. The origin theories of tektites all have serious gaps in them.
More research continues to be done, and more needs to be done.
There was a surge of study in the 1960's and 1970's. Scientists further polarized themselves into camps. Clearly the lack of close similarity to tektites of the rocks brought back was a great disappointment to lunar theorist. However, they took some comfort in the glass spheres contained in the soils of the Moon, and that the soils themselves were found to be more similar. Tektites are often collected by people which have few sources of income.
