SAMPLE DESCRIPTIONS[RDF1]





Embarcadero # 1



Meters



0 - 24		Flood plain quartz gravels.



24 - 162		Calcareous redbeds - Clay, claystone, alternating shales and sandstones.



162 - 985  	Light gay to gray black, usually firm, hard, calcareous alternating shales, siltstones and 			sandstones.



985 - 1265	Light to medium gray, arkosic, siliceous calcareous, firm to hard, alternating graywacke 		shales and sandstones.



1265 - 2189	Light to dark gray, very fine to medium grained, slightly arkosic, calcareous, firm to 			hard, blocky, fissile, alternating shales and sandstones.



2189 - 2220  	As above but sandstones contain brecciated fragments.



2220 - 2235	Grayish white to dark gray, calcareous, firm, blocky, very fine to fine grained, 				alternating shales, siltstones, and sandstones.  Interbedded in the sandstones are thin 			beds of light gray, microcrystalline, dense limestone.



2235 - 2308	Calcareous and argillaceous redbeds: Medium to dark reddish brown to orange-red, very 		fine to fine grained, angular to subangular, poor to moderately sorted, firm alternating 			shales, siltstones and sandstones.  The sandstones are generally well cemented with 			calcite or silica and have very low porosity.



2308 - 2470	As above but also containing greenish white to gray green shales and sandstones.



2470 - 2774	As above but also containing occasional white, light gray, and blue, subangular to 			surrounded, very fine to fine grained sandstones.



2774 - 3125	Calcareous and argillaceous redbeds as described between 2235 and 2308 m.  The hole 			was building angle, suggesting the bit was following bedding planes.



3125 - 4073	As above but containing abundant secondary, crystalline calcite and traces of anhydrite 			in fractures which create a sucrosic texture.  The shales are occasionally light green, 			gray, and blue.



4073 - 4159	Light to dark gray, black, slightly calcareous, carbonaceous, subangular to subrounded, 			poor to moderately sorted, firm to hard, alternating shales, siltstones, and sandstones.  			There is occasional disseminated pyrite in the sandstones.



4159 - 4204 	As above but containing 50% redbeds.



4204 - 4479 	Quartzite and quartz that appear to fill large fractures in the red beds described above.  			The quartz is clear to white, light green, very clean, and occasionally disseminated with 			pyrite.



4512 - 4534 	Quartz fault gouge.



4534 - 4580	Phyllite:  Low grade schist that is dark gray to black, poorly foliated, occasionally 			disseminated with pyrite, and firm to hard.  The phyllite contains lenses of clear to light 			green quartzite.







Raiti - Tara # 1



0 - 30		Red to yellow clay and river gravel.



30 -  503	Redbeds: Calcareous, very fine to coarse grained, poorly sorted, soft to firm, sometimes 			friable or unconsolidated, alternating shales, siltstones, sandstones, and conglomerates.  			The sandstones are cemented with calcite, anhydrite, and occasionally silica and 			hematite.  The conglomerates are clast supported in a sand matrix.  Clasts are 				subangular to surrounded and include quartz, quartzite, chert, and occasional volcanic 			and limestone detritus.



503 - 1372	Same as above except the redbeds are generally better cemented, creating dense layers 			that are responsible for the strong amplitudes between 0.45 and 0.50 seconds on the 			seismic section.



1372 - 1538	Same as above except the redbeds contain 10-20 m zones of limestone conglomerate.  			Conglomerates have a red claystone matrix.  Limestone clasts are sub-rounded, micritic, 		non-fossiliferous, clean, dense mudstone.



1538 - 1696	Redbeds: Calcareous, with crystalline calcite and anhydrite cement in microfractures, 			fine grained, poorly to moderatly sorted, friable to hard and tight, alternating shales, 			siltstones and sandstones that contain coarse fragments of quartz, quartzite, and 			limestone.



1696 - 1883	Dark brown to gray, calcareous and siliceous, very fine grained, moderately well sorted, 			friable to hard, shales, siltstones and sandstones.



1883 - 1979	Gray, green, fine grained, well sorted, calcareous and siliceous, carbonaceous with 			disseminated pyrite, slightly friable, tight shales, and sandstones.

LOGGING PROGRAMS





Embarcadero No. 1





Run no. 1 (190-1113 m), Dual induction, self potential, gamma ray, caliper, sonic and dip log.



Run no. 2 (1128-2413 m), Same as above (Dual induction, self potential, gamma ray, caliper, sonic and dip log).



Run no. 3 (2744-4269 m), same as above but without a dip log (Dual induction, self potential, gamma ray, caliper, and sonic log).



Check shot survey, (183-2763 m), The sonic log was used to interpret velocities from 2413 to 4269).
