| Comments: | Bridges et al. (2011): "Mattheddleite is very rare having only been noted on a single 4 cm specimen where it lines four 5 mm cavities as sprays of minute (<0.1 mm) needles. The matrix is iron stained quartz-galena and associated minerals are susannite, cerussite, and hydrocerussite. On the reverse of the specimen is yellow pyromorphite. Regrettably, although the specimen was found on the 90-fathom dumps, it is very similar to material from Higher Roughton Gill and the possibility of it having originated there cannot be dismissed. For this reason, the provenance is considered doubtful." | |
| Habit: | minute needles with caledonite, lanarkite, leadhillite, hydrocerussite, etc. | |
