The quarries which produce a very distinctive suite of specimens are 3 Km. east of Malad (a town in northern Bombay and the railway station closest to the quarries), Ward 38, Bombay, India.
If you were a runner involved in selling "zeolite" specimens from the quarry you got off at the Malad train station and walked or caught a motorcycle rickshaw to the quarries which are about 3km east of the railway station (you can see them on satellite images here on Mindat. If you drove in a car you went a bit further north to the little town of Kandivli (Khandivili) and then went south east a bit to reach the quarries. There are seven quarries near Malad. The #2 quarry is the one that produced all or almost all of the Yugowaralite specimens. The quarries are numbered sequentially from #1, The numbering of the quarries is now not very useful because over the course of time, they more or less merged into one another.
