Minerals have been attributed to this town using Robinson's 1825 Catalog of American Minerals as a reference. This is incorrect as Robinson was actually referring to "Saybrook" which is not equivalent to the modern town of Old Saybrook. Saybrook colony was established in 1635 and merged with the Connecticut colony in 1644. Various portions split off and became incorporated over time as the towns of Lyme (1665), Old Lyme (from Lyme) (1855), East Lyme (from Lyme) (1839), Chester (1836), Westbrook (1840), Essex (1852, known as Pettipaug, Pettypaug, or Potopaug until 1854), and Old Saybrook (1854). The remainder changed its name to Deep River in 1947. Thus minerals attributed to "Saybrook" in Robinson (1825) could include mineral localities now in any or all of these towns other than the Lymes. The reference includes entries for "Chester Parish. See Saybrook" and "Pettypaug. See Saybrook" and "Saybrook" (but no entry for Lyme).

| ⓘ Actinolite ? Formula: ◻Ca2(Mg4.5-2.5Fe0.5-2.5)Si8O22(OH)2 Description: Exact town uncertain as reference discusses "Saybrook", which covered what are now several towns. The Hebron Formation, a calc-silicate rock that crops out in most of these towns, likely hosted the actinolite. Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ Formula: ◻{Mg2}{Mg5}(Si8O22)(OH)2 Description: Exact town uncertain as reference discusses "Saybrook", which covered what are now several towns. The Middletown Formation, which underlies some of these towns, hosts anthophyllite, but it does not underlie Old Saybrook. Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ ' Formula: AB4[Si8O22]X · 8H2O Description: Almost certainly an erroneous confusion with or misspelling of anthophyllite as the local bedrock is metamorphic, not the typical basalt that hosts apophyllite. Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ 'Chlorite Group' Description: Exact town uncertain as reference discusses "Saybrook", which covered what are now several towns. Chlorite is common in all the metamorphic rocks of the area. Robinson notes that it is "in small crystals". Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ Epidote Formula: {Ca2}{Al2Fe3+}(Si2O7)(SiO4)O(OH) Description: Exact town uncertain as reference discusses "Saybrook", which covered what are now several towns. Epidote is common in all the metamorphic rocks of the area. Robinson notes that it was "crystallized". Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ Formula: MoS2 Description: The reference discusses the locality now in Essex (formerly Pettipaug), which was part of Saybrook until 1852. Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ Formula: SiO2 Description: The reference discusses its occurrence at the molybdenite locality in Essex and at the sillimanite type locality in Chester, which in 1825 were still part of Saybrook. Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
| ⓘ Formula: Al2(SiO4)O Description: Reference discusses the type locality in Chester, which was part of Saybrook until 1836. Reference: Samuel Robinson (1825) A Catalogue of American Minerals, with their localities. Boston |
