Different websites say different things on the matter.

For example:

This Website Holds that pitchblende is also known by the name Uraninite.

This Website Holds that pitchblende is a type of Uraninite.

My question is, which website is correct? I have always known the first site to be a reputable source, so I assume that this is a contentious topic.

If you search online for Uraninite then you find various websites saying that uraninite is called pitchblende.

On wikipedia you find :

Uraninite is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO2, but also contains UO3 and oxides of lead, thorium, and rare earth elements. It is most commonly known as pitchblende

even the word pitchblende will automatically redirect you to the uraninite wikipedia page .

Another trustworthy website is mindat.org : uraninite information can be found on this link:http://www.mindat.org/min-4102.html (It seems that there are various names associated to the mineral):

Re-named in 1845 by Wilhelm Karl von Haidinger for its composition containing uranium. Originally recognized before the element uranium was known and called "schwarz beck-erz" by Franz Ernst Brückmann in 1727. Subsequently described with several names including "pseudogalena" and "pitch-like zinc-blende" by Johan Gottschalk Wallerius (Vallerius) in 1747. Named pechblende by Axel Cronstedt in 1758. Named "uranerz" by Martin Klaproth after he discovered the element uranium in this mineral. Many spelling variations of the above names known.
