1 Event	2 Sample label	3 Depth sed [m]	4 Lithology (Part 1)	5 Lithology (Part 2)
107-654A	107-654A-36R-1,110	311.10	Gypsum-rich interval 5 (310-311.1 mbsf). Base of the interval and also of Unit 2, just above an unconformity. Very finely laminated medium to dark gray balatino-gypsum dominates this interval.	The color is clearly darker than in the following intervals.
107-654A	107-654A-35R-1,40	300.41	Gypsum-poor interval 4 (300.1-309.95 mbsf). The sample occurred in a pocket of secondary gypsum in a gypsiferous and calcareous mudstone.	Pyrite and secondary gypsum crystals are abundant. The latter, showing typical twinning, were picked from the sediment, washed and then analyzed.
107-654A	107-654A-34R-1,99	291.60	Gypsum-rich interval 4 (290.74-295.8 mbsf) which is dominated by white to yellowish 0.5-1 cm thick laminae.
107-654A	107-654A-33R-1,61	288.21	Gypsum-poor interval 3 (287.6-290.6 mbsf). Sample is a crystalline gypsum. Most of the interval comprises alternations of centimeter-thick well layered dark gray calcareous muds with very fine gypsiferous laminae.	White marls with abundant nannofossils occur in Section 654A-33R-1, 112-130 cm.
107-654A	107-654A-31R-1,121	277.51	Gypsum-rich interval 3 (277.3-287.6 mbsf)- The gypsum is a fine grained laminated alabastrine (balatino) type.
107-654A	107-654A-31R-1,5	276.35	Gypsum-poor interval (276.3-277.3 mbsf). The sample consists of large gypsum crystals with swallow tail twinning. Normal graded units composed of sand and silt which pass up into poorly calcareous silty mud.	A 10-cm thick microbreccia at the base of this interval is possibly of eolian origin.
107-654A	107-654A-30R-1,87	272.14	Gypsum-rich interval 2 (272-276.1 mbsf). Sample is part of a pure balatino-type finely laminated gypsum.
107-654A	107-654A-29R-2,16	263.36	Gypsum-rich interval 1 (253.5-264.42 mbsf). Sample occurs in weakly consolidated gypsiferous and dolomitic mud, and graded gypsiferous silts and muds which dominate the interval. Micro-cross lamination, ripple and flaser structures were noted.	Subvertical fractures infilled with gypsiferous silty sand record physical diagenesis. Concretions of selenitic gypsum were interpreted as chemical diagenesis.
107-654A	107-654A-27R-1,29	243.09	Gypsum-rich interval 1 (242.7-253.5 mbsf). Sample is from top of Unit 2. It is again fine grained alabastrine balatino-type gypsum.	The laminae between the gypsum can often be very calcareous, sometimes containing calcareous nannofossils.
107-653B	107-653B-28X-CC, 29	263.89	Dark gray laminated gypsum from the bottom of Hole B. The host and overlying sediments are calcareous clays/muds of grayish, brownish, and yellowish colors.	In the overlying Core 653B-27X occur at the base putrid-smelling brilliant yellow and red mud and silts, containing iron oxides, sulfur, and sulfates.
107-653B	107-653B-26X-1,89	236.20	Picked gypsum crystals with dark inclusions (similar to Kastens, Mascle, et al., 1987, Fig. 10). The host sediment is a gray calcareous gypsiferous mud progressively enriched in dolomite downsection with fewer nannofossils.
107-653B	107-653B-25X-1,24	225.97	Light brown gypsum nodules with chicken wire texture. Matrix between nodules has wavy laminations. The layering is amplified by very thin dark brown intercalations (see Kastens, Mascle, et al., 1987, Fig. 8).
107-652A	107-652A-70R-4, 116	668.76	Sedimentary-cycle 7 (Core 652A-70R; 663.1-672.8 mbsf). Sample is a grey laminated mudstone with clay horizons and displacively grown anhydrite nodules.	A minor amount of dolomite is also present. The analyzed powder was drilled from the nodular horizon.
107-652A	107-652A-44R-3,79	425.59	Sedimentary cycle 3 (Core 652A-44R, 412.1-421.8 mbsf). The drilled sample originates from a white anhydrite horizon in a gray sandy laminated mudstone with displacively grown white anhydrite nodules (see Kastens, Mascle, et al., 1987, Fig. 13).
107-652A	107-652A-42R-3,80	406.20	Sedimentary cycle 2 (Cores 652A-38R to -43R, 354-412.1 mbsf). This anhydrite is a larger nodule in the gypsiferous calcareous mudstone.
107-652A	107-652A-38R-3,111	367.81	Sedimentary cycle 2 (Cores 652A-38R to -43R, 354-412.1 mbsf).
107-652A	107-652A-38R-3,7	366.77	Both samples were deposited within two of the several described sequences (1-25 cm thick). A single sequence starts with a sharp, often scoured black gray basal contact, overlain by gypsum-bearing sands and silts,	well graded, often bedded and laminated, followed by olive layered clays and muds, and ends with crystalline anhydrite with chicken wire texture, like the two measured samples.
107-652A	107-652A-33R-3,46	318.76	Lithologic subunit IVb (286.3-334.7 mbsf). The sample is a grayish brown halite and gypsum-bearing sandy siltstone. In this subunit reversely graded sequences, water-escape structures, synsedimentary microfaults, and microbreccias were recognized.	The first occurrence of crystals of authigenic calcium sulfates and cubic dissolution molds were recovered in Cores 652A-33R to -35R.
