Brit.

/ˌparəˈdʒɛnᵻsɪs/, U.S.

/ˌpɛrəˈdʒɛnəsəs/

Inflections: Plural parageneses

/ˌparəˈdʒɛnɪsiːz/.

Origin: Formed within English, by derivation. Etymons: para- prefix¹, -genesis comb. form.

Etymology: < para- prefix¹ + -genesis comb. form.In sense 1 after German Paragenesis (A. Breithaupt Die Paragenesis der Mineralien (1849) 1). In sense 2a after French paragénésie (1875 or earlier); compare earlier paragenesic adj. With sense 2b compare paragamy n., parthenogenesis n.

a. Geology. The co-occurrence of different minerals, esp. as characteristic of the conditions of their formation; a set of minerals occurring together or with a given mineral. Also: the sequence and periods of formation of a suite of minerals formed in the same deposit.

1989 Jrnl. Petrol. 30 62 Cores of cordierites poikilitically enclosing biotite and lesser garnet, together with those inclusions, comprise part of a paragenesis in these rocks distinct from that defined by other matrix grains.

1861 Proc. Royal Soc. 11 51 Algæ and animals of every kind were arranged according to their vertical and horizontal distribution, and their natural groups and paragenesis were deduced from the above-mentioned physico-marine observations.

1986 Cultural Anthropol. 1 158 In a ‘hard science’ like geology, the coevolution of paired substances—called paragenesis—is a common object of precise study. In human history, the paragenesis of expressive form with adaptive behavior is no less real and no less common.

†2. Biology.

a. The presence in an organism of characteristics belonging to two different species, as in hybridization. Cf. paragenesic adj. Obsolete.
