The dolomite rhombs (to about 4-5 mm) are naked eye visible. For the strontianite and gmelinite you will need 10-20X. The main photo (FOV 6.7 x 4.5 mm) shows three strontianite sprays with acicular xls to 1.4 mm growing on dolomite. Strontianite is uncommon at MSH but can be locally abundant. In this case, there are only 2-3 additional, smaller, sprays. The second photo shows colorless, transparent gmelinite-Na xls (the largest 1.2 mm) growing on a do0lomite xl just < 4 mm tip to tip. The gmelinite looks yellowish because of the dolomite and is darker in parts because of pyrite “smears” on the back. The colorless nature of the gmelinite is more evident from the xls at bottom left. Gmelinite is common at MSH, and there are a few larger xls on the specimen. But it is not abundant in this case. The third photo shows the largest (~ 2 mm) gmelinite xl as well as a couple of smaller ones. The fourth photo (FOV 6.2 x 4.1 mm) shows one of the other strontianite sprays, very small and medium sized dolomite along with rosettes of a mica – probably muscovite. (According to the MSH rarity tables – Lapis 7/8 2000 – muscovite is very rare in hornfels. But that seems to be a typo. In my experience, it may not be found often, but when found it is very abundant.) Unfortunately the rosettes don’t show up well in the photo – partly because they are similar in color to the dolomite. The dark stuff is pyrite – mostly distorted. Weight 1.9 oz.
