Stratigraphy Summary
Approximately 2-3 cm of top soil containing grass roots and decayed vegetal matter was excavated throughout the trench except in W 1-4, N 1-6 where it wsa excavated in 1991 and 1993 (CA 36). Below the top soil light olive brown soil was present. It was excavated to approximatley 20 cm b.d. in N 1-6 W 8-5 whereupon this part of the trench, designated locus 2 was closed in order to concentrate on the stone formation uncovered in 1993 in meters N 3-4 W 1-3.
Large bedrock outcroppings were present in N 2-5 W 3-4.
Stone formation was approximately 80 x 50 cm and was formed by small to medium size rocks. Soil
in and around stone formation was uniformely olive brown with few carbon inclusions. As the excavation progressed, soil shifted to pale olive in N 2 W 1-3 and N 3-4 W 1. It was decided to make two section cuts, one immediately south and one immediately east of the stone formation. These cuts revealed a noticeable transition in soil, corresponding to a roughly circular lense of live brown soil under and in the immediate vicinity of stone formation. As the stone formation was lifted soil remianed olive brown wiht increasing concentration of carbon. When the depth of section cuts
was reached ( 45-50 cmb.d.), the confines of the lense were defined on horizontal plane in N 3-4, W 2-3, its diameter being approximately 1.2 m in diameter. At depth of 70 cm b.d. area of approximately 50 cm in diameter in the middle of the lense became very heavily included with carbon, although soil consistency and color remained the same. Lense became slightly narrower in diameter. At 75 cm b.d. soil abruptly shifted to olive brown with almost no carbon and 30 cm deeper became pale olive.
Soil surrounding the lense was uniformly pale olive with white and yellow calcium inclusions and
numerous rocks. galestra was encountered at 90 cm b.d.
Soil stratigraphy and soil types were analgous to the findings made during excavation of CA36 stone formation in 1993, in N 6 W 1 ( see JB IV, p. 167-229)
For the overlay of the stone formation and underlying strata see p. 127.
