unusual specimen (Medhurst collection) was found at Mannings Hill. It is a<br />
white, garnet-bearing rock, which occurs only as inclusions in <strong>the</strong> serpentinite<br />
in <strong>the</strong> vicinity <strong>of</strong> <strong>the</strong> Stony River, sou<strong>the</strong>rn Blue Mountains.<br />
Artefacts <strong>of</strong> Rocks Alien to Jamaica<br />
All <strong>of</strong> <strong>the</strong> artefacts so far described were manufactured from rocks and minerals<br />
common to Jamaica. This does not prove that <strong>the</strong>y originated in Jamaica,<br />
as <strong>the</strong> geology <strong>of</strong> this island is very similar to that <strong>of</strong> Hispaniola and Puerto<br />
Rico. Only two <strong>of</strong> <strong>the</strong> artefacts found were composed <strong>of</strong> rock that can be<br />
proven to have originated outside <strong>of</strong> Jamaica. A small, well-shaped pendant<br />
from K-13, Bellevue, St Andrew (H.R. Clarke collection), is composed <strong>of</strong><br />
granular quartzite. A similar but broken pendant was found at C-8, Wallman<br />
Town, Clarendon, by Lee (specimen no. 368). <strong>The</strong>se two small artefacts are <strong>of</strong><br />
great interest, as quartzite does not occur in ei<strong>the</strong>r <strong>the</strong> Greater or <strong>the</strong> Lesser<br />
Antilles. <strong>The</strong> rock quartzite forms from sands composed almost entirely <strong>of</strong><br />
quartz grains which ei<strong>the</strong>r are metamorphosed and recrystallized or are<br />
cemented in a sedimentary environment by silica. Quartz does not form a<br />
common detrital grain in <strong>the</strong> Greater Antilles. More than 60 million years<br />
ago, a number <strong>of</strong> large bodies or intrusions <strong>of</strong> quartz-bearing igneous material<br />
(granodiorite and tonalite) were emplaced along <strong>the</strong> Greater Antilles. <strong>The</strong>ir<br />
subsequent dero<strong>of</strong>ing and erosion provided more detrital quartz in <strong>the</strong><br />
younger sediments. Quartzite occurs in areas where <strong>the</strong> most ancient recrystallized<br />
parts <strong>of</strong> <strong>the</strong> Earth’s crust are being eroded – <strong>the</strong> nearest place being<br />
nor<strong>the</strong>rn South America. It is <strong>the</strong>refore concluded that <strong>the</strong>se two artefacts<br />
were transported to Jamaica via <strong>the</strong> Lesser Antilles from South America.<br />
Subdivision <strong>of</strong> Greenstone Group<br />
<strong>The</strong> next step in <strong>the</strong> petrographic study is <strong>the</strong> subdivision <strong>of</strong> <strong>the</strong> greenstone<br />
group. This at present covers a wide variety <strong>of</strong> rock types differing in grain<br />
size, texture, structure, composition, mineral assemblage and ability to take a<br />
polish. Separation <strong>of</strong> at least <strong>the</strong> most striking types could provide an estimate<br />
<strong>of</strong> inter-island trade or migration within <strong>the</strong> Greater Antilles (a particularly<br />
striking study could be made in Puerto Rico, near <strong>the</strong> eastern end <strong>of</strong> <strong>the</strong><br />
greenstone belt, sou<strong>the</strong>ast <strong>of</strong> which only lavas and rare cherts or jaspers are<br />
available on <strong>the</strong> volcanic Lesser Antilles). A preliminary attempt at such a<br />
study was made when eight stone celts and one pestle from Haiti were compared<br />
with <strong>the</strong>ir <strong>Jamaican</strong> counterparts in Lee’s collection. Three Haitian<br />
specimens <strong>of</strong> distinctive rock types matched exactly (by hand lens) <strong>the</strong> rock<br />
