ncat JR3 WQ1-09C Gypsum, Siderite, Bickers Quarry (Simpkins Quarry), Tokatoka, Kaipara District, Northland Region, North Island, New Zealand

Labelled as apatite but I think the long prismatic crystal is gypsum. The termination is wrong for apatite. There is greenish-brown chlorite and a brown siderite with a hollow core, left hand side of the vugh. Colourless gypsum crystals are also in the top right hand side of the vugh. Width of view 6mm. Stack of 45 images.
