"Salt" without any other qualifiers refers to sodium chloride (NaCl), which in pure form is also the mineral halite. Evaporite is the mineral produced by evaporation of seawater. It contains a large quantity of halite, but also has some other minerals in it, which vary according to the composition of the sea that evaporated. Generally, it adds calcium, potassium, and magnesium to the cations, and carbonate, sulfate, bromide, and fluoride to the anions. It is very likely to contain hydrates. As far as I know, the marketing names and terms for salts are not controlled. Someone could come up with a process to color purified table salt pink and then sell it as Himalayan salt, without it ever going anywhere near Pakistan. Someone is probably already doing that. And actually, as some evaporite deposits are not safe for dietary consumption, it is likely that mines in India and Pakistan are purifying their salt, selling most of it as iodized table salt domestically, and then recoloring some of it for export as luxury product. There are only two kinds of salt you need to worry about for cooking. "Salt", which has been purified and probably iodized, and "sea salt", which has only been processed for uniform particle sizes. You can also get pure potassium chloride (KCl) at most supermarkets, and it does taste noticeably different from pure NaCl. There is no need to buy a premium product, unless spending the extra money makes you feel good.
